建筑地基与场地地震安全性评价方法浅析

Tentative analysis on seismic safety evaluation of construction foundation and site

主要研究了高层建筑场地的两种地震安全性评价方法的应用,通过场地剪切波波速勘测,分析了舟山地区典型地层的场地类别划分方法,利用土动三轴液化试验,通过计算分析了液化判别方法,研究结果表明,采用合理的方法对场地的地震动特性进行评价是可行的,加强高层建筑地基地震安全性评价十分必要。

This thesis mainly studies the application of seismic safety evaluation methods of two kinds of high-rise construction sites, analyzes typical stratigraphic sites classification methods in Zhoushan areas by surveying site shearing wave velocity. Using soil liquefaction dynamic triaxial test, it analyzes liquefaction assessment methods by calculation. Research results show that： it is feasible to evaluate site seismic characteristics with reasonable methods; it is also necessary to strengthen seismic safety evaluation of high-rise construction foundation.
