摘要:
为分析研究三峡库区水位升降作用对库岸边坡稳定性的影响作用，通过研究三峡库区内分布广泛的须家河组（T3x）砂岩在天然状态、饱水1，2，5，10，20，30 d等不同饱水时间下的物理力学性质变化规律性，测定其不同饱水时间的含水率、吸水率及抗剪强度，预测分析砂岩抗剪强度、砂岩含水率、砂岩吸水率随不同饱水时间的变化规律以及砂岩抗剪强度随含水率的变化规律等。试验结果表明，砂岩C，Φ值与饱水时间分别呈对数和指数关系，砂岩含水率ω、吸水率ωa与饱水时间呈对数关系。应用这一规律，对于在评价库水位升降作用对岸坡稳定性的影响作用时进行岸坡岩土体的物理力学参数取值有十分重要的理论和实际意义。
Abstract:
In order to analyze the regularities of the stability of the bank slope with the change of the water-level in three gorges,the paper analyzes the mechanical regularities of T3x sandstone which is widely distributed in the three gorges in different saturated conditions such as natural,one,two,five,ten,twenty and thirty days,measured the parameter ω,ωa,shear strength in different saturated conditions.Then the paper predicts the regularities of the ω,ωa,shear strength in different saturated conditions,and the regularities of the shear strength with the change of the parameter ω;as the result,the paper indicates that the parameter C is relationship with the different saturated conditions,the parameter φ is relationship with the different saturated conditions etc.According this result,it is very important to select the mechanical parameter to assess the stability of the bank slope in the three gorges.
