| 摘 要： | 通常情况下认为碎裂结构的岩体具有非连续介质的特征。但是随着西部大量水电工程的勘查和建设,遇到了一类比较特殊的岩体,这类岩体中裂隙发育,结构面间距很小,按照国标划分为碎裂结构岩体,但是其本身又具有较高的力学性质,表现为具有较高的变形模量、抗剪强度参数和完整性系数,并且具有似连续介质的特征,这与通常的碎裂结构岩体有本质的区别。本文将利用两个实例工程对这一现象进行初步的分析,得到了水电工程可利用岩体的一种新的评价方法。

| Abstract: | Cataclastic rock mass has dominant discontinuous medium features.There are a special rock mass along with reconnaissance and building of Hydropower in the west.The rock mass should be cataclastic rock mass because of small space between discontinuities.But the rock mass differs from the common cataclastic rock masses because it has high mechanical characteristics and likely continuous medium features.The rock mass has high modulus of deformation,high shear strength and high sound degree coefficient.It is hoped to have reference to other projects.Two examples are analyzed.A new method of available rock mass in hydropower project is obtained. |

| Keywords: | Hydropower plant Rock mass structure Sound degree coefficient Space between discontinuities Mechanical characteristics of rock mass |
