摘要
将Kriging改进响应面法推广到挂篮使用可靠度分析中,研究了范和港大桥牵索挂篮的可靠度问题。通过拉丁超立方抽样选取少量均匀分布的样本点,快速拟合出接近极限状态方程的响应面,进而计算结构的可靠度。计算结果表明,Kriging改进响应面法是可行且有效的,范和港大桥挂篮在使用中具有较高可靠度。
Kriging improved response surface method （KIRSM） is extended to the reliability analysis of traveler, and used to study the reliability of traveler of Fanhegang Bridge. Some sample points are selected which are uniform distribution by the means of Latin Hypercube Sampling, and then the response surface is fitted which is close to limit state equation quickly, and the reliability is calculated finally. The results show that the KIRSM is feasible and effective, the traveler of Fanhegang Bridge possesses a high reliability.
