Research the Weathering Characteristics of Tertiary Silty Mudstone along Chengnan Freeway

Abstract:

In order to research the weathering characteristics of Tertiary silty Mudstone along Chengnan Freeway, the experiment of the engineering characteristics, the weathering durability, the weathering speed to be done for the different weathering degree silty mudstone. The test result show that when the weathering degree of the rock mass deepen, the content of clay minerals in the rock mass is increase, the activity chemical composition in the rock mass is decrease relatively, the dry density of the silty mudstone is decrease, the total porosity and the water absorption of the silty mudstone is increase, the mechanical properties is weak, the rock mass is soften and collapse easily. The weathering speed of the rock mass with the relevant to the weathering degree and the exposed area of the rock mass.
