The Relation between Moisture Content and Share Strength of Swelling Soft Rock in the North of Xianfeng Town Open-Cast Coal

Article Preview

Abstract:

We did sorts of shear strength tests in different moisture content conditions with amount of disturbed soil which was collected from the swelling soft rock in the north of xianfeng town open-cast coal. Furthermore, we analyzed the physical relationships between moisture content of the rock-soil mass and shear strength under different soaking time or different moisture content conditions. Finally, we find the shear strength of rock-soil mass drops along with the saturated degree of test specimen doubled and re-doubled. We get a conclusion that soaking of the rock-soil mass has a strong influence on the strength of rock-soil mass. The soaking of groundwater and surface water could soft the rock-soil mass, which plays an important role in controlling the stability of side slope, also in continuing slip deformation.
