摘要
国内外一些土石坝普遍选用硬岩作为筑坝材料,受岩石力学性质的影响,一些大坝选择在坝体干燥区布置软岩开挖料,取得了较好的效果。文章介绍了我国西南地区某大型水库工程砾石土心墙坝的设计实例,在分析坝址工程地质情况和石料场筑坝料源的基础上,对坝体结构进行合理分区,扩大坝体上软岩的使用范围,降低了工程成本。
Hard rock is widely used as dam building material for some earth rock dams at home and abroad.Affected by the mechanical properties of rock,some dams choose to arrange soft rock excavation materials in the dry area of the dam body,which has achieved good results.This paper introduces the design example of gravel soil core dam of a large reservoir project in Southwest China.Based on the analysis of the engineering geology of the dam site and the dam material source of the quarry,the dam structure is divided reasonably,the use range of soft rock on the dam body is expanded,and the engineering cost is reduced.
