某引水工程渡槽承台基础受力特性分析

Analysis on the Stress Characteristics of Aqueduct Cap Foundation of a Water Diversion Project

文章依托湖北省鄂北地区重要引水重建渡槽实际工程案例,结合数值模拟手段,分析了不同应力路径条件下渡槽承台基础的最大第一主应力变化情况,计算了不同荷载条件下不同基础形式的渡槽沉降情况,得出水平荷载对渡槽结构影响较大,承台具有对差异沉降的协调能力,能够有效减小渡槽基础的沉降,维持渡槽的稳定性作用的结论。

Based on the practical engineering case of the important water diversion reconstruction aqueduct in northern Hubei Province,combined with the numerical simulation method,this paper analyzes the maximum first principal stress variation of the aqueduct cap foundation under different stress paths,and calculates the settlement of the aqueduct with different foundation forms under different load conditions.It is concluded that the horizontal load has a great influence on the aqueduct structure,and the cap has the ability to coordinate the differential settlement,which can effectively reduce the settlement of the aqueduct foundation and maintain the stability of the aqueduct.
