摘要: 在对深圳断裂带构造活动性演化分析的基础上,配合现今构造应力场平面和三维数值模拟,定量计算输水隧洞不同地段轴向与最大水平主压应力方向的夹角、深圳断裂带与隧洞交汇部位的现今活动量级范围以及深埋隧洞地段现今构造应力状态,为深圳市东水西调输水隧洞工程设计和施工提供依据。

Abstract: After an analysis of the evolution of the activity of the Shenzhen fault zone numerical simulations of both plane-and 3-D present tectonic stress fields are made to calculate quantitatively the angle enclosed between the maximum horizontal principal compressive stress direction and the tunnel axis at different sections of the Shenzhen water diversion tunnel.The displacements of the faults at the intersections between them and the tunnel and the possible stress states of four deep buried sectors of the tunnel are also obtained by the modeling.The results will provide data for the design of the planned tunnel construction.
