| 摘 要： | 通过对JC可靠性分析方法研究分析,提出了一种建立于标准贯入击数极限状态方程的地震液化可靠度评估方法,并用MATLAB7.0编制了相应的地震液化概率判别程序.用该可靠性分析方法对1976年唐山地震资料进行液化概率分析,通过与实测值和规范法计算结果对比,验证了该方法的可行性和精确性,为砂土液化势评估提供了一种有效的砂土液化评价的新方法.

| Abstract: | A JC analysis method for seismic soil liquefaction,which was based on the limit state equation of blow count of SPT,was established through the research on reliabilty analysts of JC method.The corresponding programmers for computing liquefaction probability were compiled by MATLAB7.0.The results of seismic soil liquefaction analysis for the Tangshan earthquake in 1976 were compared with the measurements and requirements of the building codes.The feasibility and accuracy of this method were validated and som... |
