摘　　要：采用响应面数值模拟技术在设计验算点处拟合了代替真实极限状态曲面的响应面函数,并在此基础上运用一次二阶矩法编写MATLAB程序对架空直立式码头桩基进行了可靠度分析求解。验证了基于响应面对大型结构可靠度求解的可行性。The response surface function which replaced the real limit state curved surface was fitted at the design checking calculation point by using the response surface numerical simulation technology.And the reliability of the overhead vertical pier's pile structure was analyzed by the MATLAB program coded through first order and second moment(FOSM) method.The result indicates that it's feasible to calculate the reliability of large scale structures based on the response surface method.
