Institute of Geology and Geopmssics, Chinese Academy of Sciences, Beijing 100029

摘要

摘要: 硬粘土是介于软岩和硬土之间的一种介质, 其中含有规律分布的裂隙, 具有明显的方向性和各向异性特征; 本文从实际应用的角度出发, 提出一种适用于裂隙性硬粘土的损伤力学模型, 并应用于南水北调中线渠道边坡工程的数值模拟分析。

Abstract: Hard clay is a kind of medium between soft rock and hard soil. It contains regularly distributed cracks and has obvious anisotropic behaviours. In this paper, a damage mechanical model suitable to the cracked hard clay is presented for on engineering application. This model was used for numerical simulation of canal slope engineering in Nanyang basin. .
