[提要] 國內(nèi)外對(duì)軟粘土的震陷與計(jì)算分析還不多,我國建筑抗震設(shè)計(jì)規(guī)范也尚未評(píng)價(jià)軟粘土的震陷問題及規(guī)定其抗震措施。根據(jù)某高速公路建設(shè)的需要,研究了軟粘土在循環(huán)荷載作用下的動(dòng)力特性和計(jì)算模擬方法,進(jìn)行了震陷估算及抗震措施評(píng)價(jià),得到了一些新的認(rèn)識(shí)與結(jié)論,供地震區(qū)軟粘土震陷評(píng)價(jià)參考。
[關(guān)鍵詞] 路基 軟粘土 動(dòng)力反應(yīng) 軟化模量法 震陷 抗震措施Seismic settlement analysis of soft clay has been studied little at home and abroad.Our building aseismic design criterion has not judged seismic settlement of soft clay and defined relevant aseismic means. Based on the construction demands of a certain freeway, the dynamic characteristics and computation method of soft clay under cyclic loading are investigated,and estimation of seismic settlement and evaluation of aseismic means are carried. Some new realization and findings are obtained, which can be referred in other softclay areas with frequent earthquake.
Keywords: embankment; soft clay; dynamic response; softening modulus method; seismic settlement; aseismic means參 考 文 獻(xiàn)
