摘要:
拱坝坝肩地质条件对拱坝的正常运行至关重要,拱坝失事很少是由于拱坝自身问题引起,大部分是由坝肩失稳造成的。在拱坝基础较差的情况下,传力洞是一种有效的加固措施。目前,传力洞已广泛运用于坝肩处理中,但是其研究明显落后于应用。因此,研究复杂地质条件下拱坝坝肩的稳定意义重大。以葫芦口水电站为研究对象,依据有限元分析软件ANSYS计算结果,使用刚体极限平衡法验证传力洞对拱坝坝肩的增稳效果,认为传力洞能够改善拱坝的受力情况,并提升坝肩基岩的稳定性。
Abstract:
Geological conditions of the dam abutment are very important to the normal operation of the arch dam,the arch dam accidents are rarely due to their own problems,they are mostly caused by the instability of the dam abutment.In the case of poor dam foundation,concrete plug will be an effective reinforcement method.At present,concrete plug has been widely used,but the research on it is far behind the application.Therefore,the study on the stability of arch dam abutment under complicated geological conditions would be of great significance.In this paper,based on the results of Hulukou hydropower station calculated by finite element analytical software ANSYS,the rigid limit equilibrium method is applied to testify the effect of concrete plug on arch dam.The result shows that concrete plug could improve the force situation of arch dam and the stability of dam abutment.
