Abstract
According to characteristics of the thick overburden dam and the current and main problems on seepage of the thick overburden concrete face rock-fill dam, this paper takes finite element method to analyze the three-dimensional seepage field of thick overburden CFRD after the joint sealing failure, and studies the seepage field distribution of the CFRD after sealing failure, and analyzes the sealing failure position and influences of seam length on each seepage elements variation. In this paper, taking the thick overburden CFRD in xinjiang as an example, effects of the joint sealing failure on seepage related factors are discussed , the change rules of saturated faceseepage discharge and seepage gradient of the thick overburden CFRD are obtained by studying,. The research results can provide a reference for a parallel engineering design and construction.
