The researching fields involve its engineering characteristics, weathering durability and weathering speed. The engineering characteristics were revealed by testing mineral composition, chemical composition and mechanical properties of rock mass with different weathering degrees. The weathering durability was shown by testing compressive strength and slake durability of different rock samples. The weathering speed was determined in four different experimental conditions for the weathering rock. The test results show that with the growth of weathering degree of the rock mass, the content of clay minerals in the rock mass increases, the chemical composition with high activity in the rock mass decreases relatively, the dry density of the silty mudstone decreases, the total porosity and the water absorption rate of the silty mudstone increases, the mechanical properties are weakened, and the rock mass becomes easy to soften and collapse. At the same time, the weathering speed of the rock mass is related to the weathering degree and the exposed area of the rock mass. The research findings provide some theoretical basis for understanding the Tertiary Pelitic Siltstone and solving related problems in practical engineering., authors=null, authorsList=null,

articleAbstract=为研究第三系粉砂质泥岩的风化特性，通过不同的试验，对不同风化程度的粉砂质泥岩岩体分别进行工程特性、风化耐久性和风化速度研究。通过测试风化岩体的矿物成分、化学成分及物理力学性质来对其工程特性进行研究；通过抗压强度试验、软化崩解性试验对其风化耐久性进行研究；通过对所处4种不同环境的风化岩石的观测试验来对其风化速度进行研究。试验结果表明：随着岩体风化程度的加深，岩石中黏土矿物含量增加，活动性强的化学成分相对减少，岩石干密度降低、总孔隙度和吸水率增大，力学性能降低，岩体更容易软化崩解。岩石的风化速率与自身的风化状态和暴露的面积有关。,
