Abstract
A number of high pressure triaxial wetting tests were performed with two sets of rockfill material from Zhangfeng Reservoir in order to in-vestigate the shear strength feature after wetting and the relationship between slaking axial strain ,volumetric strain and ambient pressure and stress level. Furthermore,this article compared the related data of triaxial wetting text and triaxial compression text. It’s found that the different stress levels have little influence on the shear strength after wetting. Besides,it’s showed that the deformation characteristic of slaking axialstrain,volu-metric strain is related to not only ambient pressure but also stress level. When the stress level is low,volumetric strain will not change with the change of ambient pressure. While when the stress level is relatively high,the variation trend of volumetric strain is growing with the increase of ambient. The variation quantity of volumetric under low stress level with the change of ambient pressure is very small. Under the same test condi-tion,and the strength values of consolidated drained,triaxial wetting text and consolidated aerofluxus increase successively.关键词
