%X In this paper,the collapse test with increasing moisture for Weibei Zhangqiao unsaturated loess is studied. The curves of shve-p,shve-(au-wu),shse-q,as well as shse-(au-wu) are obtained respectively. The parameters defining effective stresses,xp and xq,are determined through curves of shve-px and shse-qx. Using these results,the variation of effective stresses under collapse condition with increasing moisture for unsaturated intact loess can be estimated.
