Study on the Application of Soft Rock Dam Construction Technology in a Faced Rockfill Dam
In this paper,Duncan Chang's e-b model and MIDAS GTS NX software-a general geotechnical analysis program-are employed to construct a three-dimensional model of the dam.Four distinct zoning schemes of soft rock are designed:soft rock is utilized in the main body,main rockfill area,secondary rockfill area,and 510~610 m elevation part of the secondary rockfill area.The stress and deformation of faced rockfill DAMS under these four schemes is then examined.It is concluded that the distribution of dam stress and deformation with soft rock is similar to that with traditional rockfill.The use of soft rock in some parts of the secondary rockfill area can greatly reduce the stress and deformation of the dam,and it is safe and feasible to fill the dam body with high face.The analysis results have certain reference value for engineering design optimization,similar engineering reference and engineering safety assurance.
