摘要:
通过对改进一次二阶矩可靠性分析方法进行研究,提出了一种基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Matlab 7.0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年河北唐山大地震的资料进行了液化概率分析,并与实测值和规范判别法计算结果进行了对比。结果表明:该方法具有可行性和精确性,为砂土液化势评估提供了一种有效的新方法。
Abstract:
An improved linear second order moment method for seismic sandy soil liquefaction, which was based on the limit state equation of blow count of standard penetration test(SPT), was established through the research on reliability analyses of improved linear second order moment method. The corresponding programs for computing liquefaction probability were compiled by Matlab7.0. The results of liquefaction probability analysis for Tangshan earthquake, Hebei Province in 1976 were compared with the measurements and requirements of the building codes discrimination. The results show that this method is feasible andaccurate, and it is proved to be an efficient method to evaluate indeterminacy sandy soil liquefaction.
