中文摘要：

层间错动带是影响边坡稳定性的重要因素之一,掌握层间错动带工程性状是大型水电工程建设中的一项重要内容.以金沙江某大型水电站工程为依托,对该工区玄武岩岩体层间错动带进行室内试验和现场变形试验,研究其变形机制.根据试验数据绘制出应力-应变曲线,分析层间错动带的变形过程,通过对比和归纳,得出层间错动带的水文情况、带内物质种类及含量是影响层间错动带变形特性的主要因素.

英文摘要：

The interlamination disturbed belt is one of the important factors that affect slope stability, and grasping the engineering characteristics of interlamination disturbed belts is a very important work during the construction of large hydropower projects. In the paper, taking some large hydropower project in the Jinsha River as an example, the laboratory experiment and the field deformation test on the basalt interlamination disturbed belts were carried out to study their deformation mechanisms. The stress-strain curves were mapped by using experimental data, and the deformation processes of the disturbed belts were analyzed. By comparision and induction of the stress-strain curves, it is reached that hydrologic conditions of interlamination disturbed belts, and the kinds and contents of materials in disturbed belts are the main influence factors on deformation characteristics of interlamination disturbed belts.
