【摘要】 该文通过对改进一次二阶矩法可靠性分析研究,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。用该方法的判别结果与实测结果一致,并且能计算出液化概率,减小了误判率,弥补了确定性方法的不足,为砂土液化势评估提供了一种有效的不确定性砂土液化评价的新方法。更多还原

【Abstract】 Through the reliability analysis on the improved linear second order moment method,based on the limit state equation of blow count of SPT,a method of reliability assessment on seismic liquefaction is established.The discrimination results coincided with the practical results,and the method can also compute the liquefaction probability,decrease the misjudgment rate,make up the shortages of determinacy method.It provides an efficient method to assess indeterminate sandy soil liquefaction.更多还原
