天然地基浅基础的震害分析

The Seismic Damage Analysis of Shallow Foundation on Natural Subsoils

  • 摘要: 本文总结了天然地基浅基础的震害经验,从宏观上讨论了地基基础的震害机理,以及相应的发生条件。并指出,除了含饱和砂土或粉土地基,软粘性土地基和严重不均匀地基外,一般低层房屋的天然地基浅基础抗震性能良好,不易产生地基震害,只要静力设计合理,可不作抗震验算。最后,指出了天然地基浅基础抗震研究应着重注意的几个问题。

     

    Abstract: Based on macrscopic earthquake damage data of the common low buildings and structures, the damage experience of the shallow foundation on natural subsoils is summarized systematically and the damage mechanismand the related damage condition are analyzed. The results obtained show that the except for those sites composed of sandy or silt soils,soft clayey soils and extremely nonuniform soils,the aseismic behaviour of shallow foundation onnatural subsoils during earthquakes is good, and it is unnecessary to perform earthquake resistance analysis,providedthat it is well designed under static load. Finally,the authors point out some important problems for seismic be-haviour analysis of shallow foundation on natural subsoils。
