Researches on structural characteristics of the concrete crushing-type side wall and its influence on the stress-strain of Shuibuya CFRD

Advanced grid discreteness technique and the method to solve large scales of equations were used for the researches on structural characteristics of the concrete crushing-type side wall and its influence on the stress-strain of Shuibuya CFRD. Computational results indicate that the concrete crushing-type side wall can not only replaces the procedure of bedding material extra-filling, scaling, dressing, roller compacting and slope face protection to quicken the schedule and enhance and guarantee the construction, but also improve the stress and deformation situation of the face. In most of the time the concrete crushing-type side wall works in a low stress level, the material properties close to plain concrete.
