| 摘 要： | 某RCC重力坝坝基巨型溶蚀大厅规模大,坝基以下岩体厚度小,发育深度大,坝基开挖爆破导致洞顶以上岩体松动,存在坝基塌陷的安全隐患.在充分研究区域地形地质条件的基础上,采用三维非线性有限元法研究了不同施工方案下坝基巨型溶蚀大厅的应力场、位移场及破坏区分布,并在此基础上提出溶蚀大厅的加固处理方案及喷锚支护参数.

| Abstract: | A RCC gravity dam foundation had a large-scale giant dissolution hall;Its rock mass thickness thin below the dam foundation,developing depth larger;The dam foundation excavation blasting had made the rock mass loosening over the top of the cave： There are security risks of the collapse of the dam foundation.With different construction schemes,the stress field,topographic and geologic conditions of the dam foundation with giant dissolution hall was fully researched： A three-dimensional nonlinear finite element method was used to study the displacement field and damaged distribution,based on the dissolution of the reinforcement of the hall processing solutions and spray anchor support parameters. |
