The pseudo - static method ( static method in brief ) is now currently adopted in seismic analysis of retaining structures for some well known limitation 受各種條件限制,擋土墻的抗震驗(yàn)算,仍普遍采用擬靜力法(以下簡(jiǎn)稱靜力法) 。
The earthquake force was ignored during designing midget pump station , while the pseudo - static method just gave approximate calculation to the large and medium pump station ever 在以往的泵站設(shè)計(jì)中,對(duì)于小型泵站,一般不考慮地震力;對(duì)于大中型泵站,即使考慮地震載荷大多都運(yùn)用擬靜力法,進(jìn)行大致的近似計(jì)算。
Evaluate the conclusion of pseudo - static method and dynamical finite element , and the security of manla rockfill dam under earthquake condition , give design scheme of the manla dam according to the analysis result 通過(guò)擬靜力法和動(dòng)力有限元法得到的計(jì)算成果進(jìn)行的對(duì)比分析,對(duì)滿拉堆石壩在地震作用下的安全性進(jìn)行了綜合評(píng)價(jià),根據(jù)分析結(jié)果對(duì)工程設(shè)計(jì)提出措施。
Utilizing finite element method , found the safety factor of the dam slope . evaluate the conclusion of pseudo - static method and dynamical finite element , and the security of hada mountain embankment dam under earthquake condition 對(duì)擬靜力法和有限元法得到的計(jì)算成果進(jìn)行了對(duì)比分析,對(duì)哈達(dá)山土壩在地震作用下的安全性進(jìn)行了綜合評(píng)價(jià),根據(jù)分析結(jié)果對(duì)工程設(shè)計(jì)提出了一些建議。
The thesis mostly work is mathematical analysis , give some basic information of the research object - hada mountain embankment dam , determinate the research task and the analyses condition . utilizing pseudo - static method theory , calculated the safety factor for the dam slope , give a primary conclusion . utilizing static finite element method based on duncan - chang hyperbola model , found the static stress field , make the foundation for dynamical finite element analyses 采用等效線性模型,用計(jì)算土石壩地震反應(yīng)的動(dòng)力有限元程序,對(duì)哈達(dá)山土壩進(jìn)行了動(dòng)力有限元分析,得到了壩體的動(dòng)應(yīng)力場(chǎng)分布、加速度場(chǎng)分布,為動(dòng)力有限元法計(jì)算壩體穩(wěn)定打下基礎(chǔ)。
