【摘要】 水库蓄水后引起邻近区域地下岩体应力场的变化。沿深度方向岩土体表现为非均匀性。借助层状材料基本解发展了非均匀地基应力场和位移场的计算方法。然后,以紫坪铺水库为例分析了蓄水后水库附近岩层内应力场的变化。结果显示,库区内地表以下岩土层的非均匀性对于计算结果有明显的影响。更多还原

【Abstract】 The impounding of reservoir induces the variation of stress field in rocks in the neighbourhood of reservoir.The rock and soil masses below the ground surface are heterogeneous along the depth.This paper develops a numerical method for stress and displacement fields of a semi-infinite layered foundation by using the foundational solutions of layered materials.Then an example of Zipingpu reservoir is used to analyze the stress variation after reservoir impounding.It is shown that the heterogeneity of rocks below the ground surface area exerts an obvious influence on stresses.更多还原
