Abstract:

A new method for calculating foundation settlement reliability is proposed. The kernel technique is based on modified Cam-Clay model in FLAC and least squares support vector machine (LSSVM) combined with MCS. The sensitivity of parameters involved in modified Cam-Clay model is analyzed; and the sensitive parameters are chosen as random variables. The stochastic variables are sampled according to the probabilistic distribution. A program is programmed to calculate the reliability by Matlab. The results show that the method of MCS combined with LSSVM is worth to study for reliability analysis of soft foundations settlement.

Key words: modified Cam-Clay model, settlement, reliability, LSSVM, MCS
