摘要
胶凝砂砾石坝(简称CSG坝)是一种新坝型,其基本剖面是上下游坝坡大致对称的梯形,筑坝材料采用价格低廉的低强度胶凝砂砾石料,CSG坝具有施工简便、造价低廉、对环境负面影响小等特点。本文以那恒水库工程为例,采用有限元数值模拟方法,分别计算分析了坝体及坝基弹性模量变化对大坝应力及变形的影响。
Cement-sand-gravel dam（CSC dam for short） is a new type dam.The basic profile is a trapezoid shape with basically symmetrical upstream and downstream dam slopes.Low strength cement-sand-gravel with cheap price is adopted for building the dam.CSC dam is characterized by convenient construction,low cost and low negative influence on environment,etc.In the paper,Naheng Reservoir Project is adopted as an example.Finite element numerical simulation method is adopted for respectively calculating and analyzing the impact of dam body and dam foundation elastic modulus on dam stress and deformation.
