摘要
分析了《建筑抗震设计规范》中砂土液化危害性评价方法的不足,通过确立液化土层在不同震害模式情况下的液化震陷计算值,建立了以震陷值S为指标的浅基础水平场地地基液化危害性评价等级,得到了其评价程序。
The limitation of the hazard evaluation method of sand soil liquefaction in the 〈Code for seismic design of buildings〉 （GB50011-2001） is analyzed in this paper. By establishing the seismic settlement value under the difference modes of earthquake disaster, the hazard evaluation grade and process for liquefaction of sand soil for level grounds with shallow foundation are found.
