摘要
小湾拱坝最大坝高292.0m,坝肩槽开挖所形成的高边坡达400多米,其稳定性至关重要。结合小湾坝址区的地形、地质条件,建立三维有限元模型,研究在逐级开挖过程中边坡的稳定性,揭示边坡失稳的可能形式及部位,在此基础上提出并优化高边坡的加固措施。
With the maximum dam height of 292.0m, the excavation of dam abutment formed a side slope as high as more than 400m, whose stability is of vital importance to the dam safety. By establishing a 3D finite element model, taking into account the topography and geography conditions of the dam site, the stability of side slope in each excavation process is studied in this paper to reveal the possible failure types and locations of the side slope, and the optimized reinforcing measures are presented on this basis.
