Nyiv Seismic Isolation Industry Overview

Nyiv yog ib lub teb chaws tshaj plaws nyob rau hauv lub ntiaj teb noseismic cais thiab kev co tswj technology. Vim nws qhov chaw nyob ntawm Pacific Ring of Fire, Nyiv tau ntsib av qeeg ntau zaus ntawm qhov sib txawv. Yog li ntawd, nws tau tsim ib qho kev lag luam siab heev rau kev tiv thaiv vaj tse, txuas hniav, thiab infrastructure los ntawm seismic txaus ntshai.

Lub hauv paus ntawmseismic caissuav nrog kev ntxigcov khoom siv-isolators thiab dampers-nruab nrab ntawm ib lub qauv thiab nws lub hauv paus lossis hauv lub superstructure. Qhov no txo ​​cov av qeeg xa mus rau hauv lub tsev, txo cov kev xav tau ntawm cov qauv, thiab pab tiv thaiv lub neej thiab khoom. Hauv Nyij Pooj, kev cais tawm seismic tau siv txij li xyoo 20th lig, nrog kev loj hlob sai tom qab xyoo 1995 Hanshin-Awaji Av qeeg thiab kev saws me nyuam thoob plaws tom qab 2011 Great East Nyiv Av qeeg.

Cov Japaneseseismic cais kev lag luamtau nthuav dav vim muaj ntau tus tsav tsheb tseem ceeb:

- **Seismic Hazard:**Nyiv tau raug rau qee qhov kev pheej hmoo seismic siab tshaj plaws hauv ntiaj teb.
- **Qhov Kev Ua Tau Zoo:**Cov tsev nrogcais systemsua tau zoo dua nyob rau yav dhau los av qeeg, convincing tswv thiab regulators ntawm tus nqi ntawm cov cuab yeej technology.
- **Txoj cai thiab ntawv pov thawj:**Ministry of Land, Infrastructure, Thauj thiab Tourism (MLIT) tau tsim cov ntawv pov thawj rau cov khoom siv, txhawb nqa kev saws me nyuam.
- **Public Awareness:**Kev tshaj xov xwm ntawm cov ntaub ntawv kawm tiav tau txais kev lees paub zoo dua.

Cov qauv kev saws me nyuam qhia tau siv dav hauv tsev kho mob, chaw kho mob xwm txheej ceev, tsoomfwv cov tsev, thiab tsev cia puav pheej. Cov tsev nyob thiab cov tsev nyob tau raug cais tawm, tab sis lub khw tseem ceeb nyob hauv qhov tseem ceeb thiab siab - cov khoom muaj nqis.

Kev ua lag luam Nyij Pooj siv ntau yam khoom siv raws li cov kev xav tau tshwj xeeb:

- **Lead Roj Hmab Bearings (LRB):** Cov no muaj xws li alternating txheej ntawm ntuj roj hmab thiab steel daim hlau, feem ntau nrog ahlau pluglos muab lub zog dissipation. Dav siv nyob rau hauv ob lub tsev thiab txuas hniav.
- **Siab -Damping Rubber Bearings (HDRB):**Muab siab damping tsis muajcov cores, txo kev txhawj xeeb txog kev tu.
- **Tsawg-Damping Rubber Bearings (LDRB):**Siv qhov twg lub sij hawm cais tawm ntev dua thiab yuav tsum muaj kev hloov pauv loj dua.
- **Kev sib txhuam Pendulum Bearings (FPS):**zawv zawg bearings uas cia siab rau kev sib txhuam thiab lub ntsej muag kheej kheej los muab kev ruaj khov rov qab los. Kev siv ntau ntxiv hauv cov choj loj thiab cov qauv siab.
- **Hybrid Systems:**Roj hmab bearings ua ke nrogviscous damperslos yoghlau damperskom sib npaug yooj yooj yim thiab lub zog dissipation.
- **Viscous Fluid Dampers:**Cov khoom siv hydraulic uas nqus lub zog seismic thiab qee zaum ua ke nrogbase isolatorsrauhybrid kev daws teeb meem.
 

Kev ua tau zoo-raws li kev tsim seismic yog cov qauv hauv Nyiv. Lub hom phiaj tseem ceeb yog:

- **Kev Nyab Xeeb Lub Neej:**Ua kom lub tsev ruaj khov thiab muaj kev nyab xeeb khiav tawm.
- **Nyob tam sim no:**Tseem ceeb heev rau tsev kho mob thiab kev puas tsuaj - chaw teb.
- **Kev tiv thaiv tsis yog-Cov khoom siv:**Tsev khaws puav pheej, cov chaw khaws ntaub ntawv, thiab cov chaw soj nstuam tsom kom txo qis kom nrawm los tiv thaiv cov cuab yeej rhiab heev.
- ** Tus Nqi Zoo:**Cov tswv sib npaug tus nqi pib ntawm cov khoom siv uas xav tau ntev - cov txiaj ntsig, suav nrog txo nqi kho tom qab av qeeg.

Cov txheej txheem tswj hwm thiab kev tswj hwm ntawm Nyij Pooj yog lub ntiaj teb muaj kev cuam tshuam:

- **Txoj Cai Tsim Qauv:** Lub hauv paus ntawm Nyij Poojseismic tsim system, suav nrog kev cais tawm raws li kev lees paub tsim qauv.
- ** MLIT Certification:** Cov cuab yeej yuav tsum tau kuaj thiab ntawv pov thawj los siv hauv kev tsim kho. Qhov no suav nrog kev xeem shear, check check, thiab kev txheeb xyuas qhov muaj peev xwm hloov chaw.
- **JSSI (Japan Society ofSeismic Isolation) Cov lus qhia: ** Muab cov qauv tsim, kev sim, thiab cov lus pom zoo rau cov kws tsim khoom thiab cov chaw tsim khoom.
- **Influence on International Standards:** Japanese kev txawj ntse cuam tshuam ISO 22762 (elastomeric seismic isolators) thiab lwm cov qauv thoob ntiaj teb.
 

Nyiv hais txog kev sim nruj thiab kev saib xyuas ntev ntev:

- **Kev xeem cov khoom:** Cyclic shear tests, vertical load verification, and long-term creep tests.
- **Tag nrho-Kev ntsuas qhov ntsuas:** Cov chaw sim loj loj rov tsim dua cov ntaub ntawv av qeeg thauj cov keeb kwm txhawm rau txheeb xyuas qhov kev ua haujlwm cais tawm.
- ** Durability:** Roj hmab tebchaw raug kuaj rau ozone tsis kam, thermal stability, thiab qaug zog.
- **Kev tu thiab tshuaj xyuas:** Cov neeg cais tawm yog tsim los rau 50-100 xyoo kev pabcuam nrog kev tshuaj xyuas ib ntus. Cov ntawv cog lus saib xyuas feem ntau suav nrog cov txheej txheem rau kev hloov lossis kho dua tshiab.
 

Ob peb lub cim tseem ceeb hauv Nyij Pooj qhia txog kev ua tiav ntawm kev sib cais seismic:

- **National Museum of Western Art (Tokyo):** Retrofitted nrog lub hauv paus cais los tiv thaiv kab lis kev cai cuab yeej cuab tam thiab architectural cuab yeej cuab tam.
- **Ishinomaki Red Cross Tsev Kho Mob:** Kev ua haujlwm txuas ntxiv tom qab av qeeg xyoo 2011 ua tsaug rau kev nyob ib leeg.
- ** Cov Kev Pabcuam Vaj Tse:** Ntau txhiab lub tsev nyob tau nruab nrog cov me me - teev cais tawm, qhia txog qhov ua tau ntawm cov nplai me me.
- **Infrastructure Projects:** Ntau tus choj Nyij Pooj siv cov kabmob sib cais kom txwv tsis pub muaj seismic rog thiab txuas ntxiv lub neej kev pabcuam.
 

Cov khoom siv saw muaj xws li:

- **Cov chaw tsim khoom:** Cov tuam txhab Japanese tshwj xeeb tsimCov elastomeric isolators, cov cores, thiabzawv zawg bearings.
- **Material Suppliers:** Rubber producers thiab steel suppliers tseem ceeb heev rau kev ua haujlwm ntawm cov cuab yeej.
- **Testing Laboratories:** Cov tsev kawm ntawv qib siab thiab cov koom haum tshawb fawb muab kev lees paub ywj pheej.
- **Cov tuam txhab tsim kho:** Cov neeg cog lus dav dav muab cov cuab yeej siv rau hauv cov phiaj xwm loj -.

Nyiv kev lag luam feem ntau yog tus kheej - txaus tab sis nce ntxiv nrog kev sib koom tes thoob ntiaj teb.
 

Lub Japanese seismic cais kev lag luam yog hloov zuj zus nyob rau hauv ntau cov lus qhia:

- **Hybrid Solutions:** Ntau lub tsev siv ua ke ntawmcais tawm thiab cov khoom siv hluav taws xob dissipation.
- **Kev ua tau zoo-Raws li Tsim:** Ua kom pom tseeb ntawm kev txwv kev nrawm los tiv thaiv cov cuab yeej rhiab heev.
- **Retrofit Market Loj hlob:** Cov tsev qub, tshwj xeeb tshaj yog cov tsev kho mob thiab cov khoom siv kab lis kev cai, tau hloov kho nrog cov kab ke cais.
- **International Influence:** Japanese xeem raws tu qauv pab tsim ISO thiab lwm yam qauv thoob ntiaj teb.
- **Sustainability:** Kev tshawb fawb txuas ntxiv ntawm cov khoom siv rov ua dua tshiab rau cov khoom sib cais thiab ib puag ncig tus phooj ywg damping compounds.
 

Thaum qhia txog kev cais tawm hauv Nyij Pooj lossis xa khoom siv thev naus laus zis, engineers yuav tsum:

1. Txheeb xyuas MLIT ntawv pov thawj ntawm txhua yam khoom siv.
2. Thov cov ntaub ntawv qhia txog kev tivthaiv thiab kev xeem.
3. Txhais lub hom phiaj ua haujlwm seismic kom meej.
4. Xyuas kom muaj kev saib xyuas meej thiab kev soj ntsuam nyob hauv qhov chaw.
5. Xaiv cov neeg cog lus uas tau ntsib nyob rau hauv kev rho tawm rov qab rau cov cuab yeej cuab tam lossis cov chaw tseem ceeb.

Nyiv covseismic cais kev lag luamyog ib qho ntawm cov qib siab tshaj plaws nyob hauv lub ntiaj teb, txhawb nqa los ntawm ntau xyoo ntawm kev tshawb fawb, cov qauv nruj, thiab ua pov thawj kev ua tau zoo hauv av qeeg loj. Nrog txuas ntxiv kev tsim kho tshiab, Nyiv tseem yog ob qho tib si thoob ntiaj teb cov ntsiab lus siv thiab ua tus thawj coj ntawm kev ua haujlwm siab -seismic tiv thaiv technology. Nws lub hwj chim txuas mus dhau lub teb chaws ciam teb los ntawm cov qauv thoob ntiaj teb, kev xa tawm, thiab kev sib koom tes thoob ntiaj teb.
