活动断裂对深埋隧洞影响的研究概述

General introduction to the effect of active fault on deeply buried tunnel

简要叙述了南水北调西线工程面临的活动断裂的问题;介绍了活动断裂的运动方式、几何特征、运动的力学机制及其与地震的关系;详细讨论了活动断裂对隧洞工程的影响机理,并且总结了活动断裂的研究手段,系统地阐述了关于活动断裂的数值模拟方法并提出了有待进一步解决的问题。

In this paper the question of active faults in the engineering project of water diversion from the upper Yangze River into the Yellow River is introduced. Then the geometry type, the motion mode and the mechanism of the active faults and the relationship of active faults and earthquake are reviewed. How the active faults influence the tunnel project are discussed, and the research ways especially numerical simulation about active faults are summarized. Finally, the problems necessary to be solved in the future are presented.
