边坡开挖优化设计探讨

在水利水电工程和路桥工程中,不可避免的存在边坡开挖问题.而在边坡开挖中应遵循"少开挖,少扰动自然边坡"的原则."扇子面"开挖理念,可在很大程度上减小坡体的开挖量,尽量少地扰动自然坡体,保护生态平衡,降低边坡开挖及处理费用,加快施工进度,尽早创造效益.

Discussion on optimal design of slope excavation

Slope excavation is necessary for water and hydropower projects,as well as road and bridge projects.The principle of "less excavation and less disturbance" shall be followed in slope excavation.In the concept of "sector surface excavation",the excavation of slope body can be reduced greatly,and disturbance to natural slope may be as less as possible so as to protect ecological balance,reduce slope excavation and treatment expenses,accelerate the construction progress and bring about economic benefits as ear...
