摘要
以大型有限元软件ANSYS为平台,考虑中期导流影响对某碾压混凝土坝进行仿真计算。根据仿真分析结果,中期导流对坝体温度应力影响由坝体表面至坝体内部逐渐减弱,主要影响范围为坝体表面5~10 m;整个导流过程中,坝体上游表面应力增大0.25 MPa左右。
Simulating calculation of RCC dam was conducted with finite element software ANSYS, taking into account the influence of mid-diversion. The results of simulation demonstrate the influence of mid-diversion on temperature stress gradually decrease from dam surface to dam interior, the major affected thickness is 5~10 mm on dam surface. During the whole mid-diversion period, the stress on the upstream dam surface increased about 0.25 MPa.
