A SIMULATION STUDY OF PHYSICAL MECHANICAL PROPERTIES OF INTERCALATED GOUGE IN LAYERED WEAK ZONES

摘要: 软弱层带夹泥物理力学参数是评价岩体稳定性的基础。研究表明，在天然围压条件下，软弱层带夹泥的物理力学性质与其所承受的围压具有良好的相关性。因此，本文提出应用土工压缩定律及重力压密机制在室内对夹泥的物理力学特征进行仿真研究，并对仿真效果进行了评价。这为软弱层带夹泥物理力学参数的评价、预测提供了新的途径。

Abstract: The physical mechanical parameters of intercalated gouge in layered weak zones are the basic parameters for evaluation of rockmass stability. A large number of studies show that there is a better relationship between the physical mechanical properties of intercalated gouge and its natural confining pressure.Therefore,the simulation study of intercalated gouge was done in labortory, by using the compression law of soil and the principle of gravity compaction of sediments, and the simulation effectiveness is evaluated. The result provides a new way for evaluating and predicting the physical mechanical parameters of intercalated gouge in layered weak zones.
