以建于陡峭建基面上的溢洪道挑坎为研究对象,针对工程运行中的水流脉动问题和可能的地震作用,利用三维有限元和刚体极限平衡理论相结合的方法,研究了挑坎的动力稳定性。计算结果表明,建于陡峭建基面上的溢洪道工程侧向稳定是抗滑稳定的薄弱环节,提出的加固措施对提高工程的抗滑稳定效果较好,为类似工程的设计与建设提供了借鉴和参考。
Taking the spillway embankment built on the steep foundation as the research object, aiming at the water flow pulsation problem and possible earthquake action in the engineering operation, the author used the combination of the three-dimensional finite element and rigid body limit equilibrium theory stability. The calculation results show that the lateral stability of the spillway project built on the steep foundation surface is the weak link of the anti-skid stability. The proposed reinforcement measures have a good effect on improving the anti-skid stability of the project, which provides a reference for the design and construction of similar projects.
