摘　　要：通过运用三维有限元法对预应力混凝土渡槽结构的受力性能进行分析,对预应力钢筋混凝土渡槽的非线性特性进行了数值模拟,将得到的数值模拟解与按结构规范计算的结果比较表明:内力及配筋分布比较合理,混凝土应力满足规范要求。依此证明所采用的渡槽结构形式及尺寸、预应力筋的布置方案是合理的,渡槽结构应力、变形满足规范要求。The static structure is analyzed by using 3D finite element method ANSYS for pre-stressed concrete aqueduct structures in this paper. The numerical simulation of the nonlinear characteristics of reinforced concrete aqueduct is investigated. Numerical simu lation results are compared with the solution according to structural calculation criteria ,an analysis and calculation of the two calcula- tion methods show that the distribution of the internal forces and steel bars reinforced are reasonable and the stress in the concrete meets the requirements of specification. Type, size and pattern of pre-stressed bars for the aqueduct structure are justified and its stress and deformations meet standard requirements.
