裂隙岩体在受荷条件下的变形特性分析

Research on deformation character of cracked rockmass under loading and unloading

摘要: 在建立裂隙岩体概化模型的基础上 ,运用线弹性断裂力学理论详细推导了裂隙岩体在加荷和卸荷条件下的变形计算解析式 ,为了验证其可靠性 ,对两种裂隙分布的石膏模型进行了实验 ,实验数据与理论计算结果基本吻合

Abstract: This paper gives a mechanical model of cracked rockmass under loading and unloading.An experimental research on two kinds of gypsum model has been conducted,and the experimental results is consistent with the theoretical predictions.
