Abstract:The concrete crushing-type side wall technology is a new method for constructing the upstream side-slope of concrete face rockfill dam(CFRD). Compared with the traditional method,this technology is obviously more advanced such as enhancing the project quality,quickening the pace,increasing the safety of river diversion and etc.. Further more,the technology has simplified the construction procedure and cut down the construction cost. However,It¢s still uncertain about the effect of the concrete crushing-type side wall on CFRD,particularly on its stress-strain. This paper,applying the advanced grid discreteness technique and the method to solve large scales of equations,researches the stress-strain of Shuibuya CFRD based on the concrete crushing-type side wall technology. Through calculating,it indicates that the concrete crushing-type side wall can not only replace the procedure of bedding material extra-filling,scaling,dressing,roller compacting and slope face protection,so as to quicken the schedule and enhance and guarantee the construction,but also improve the stress situation of the face and its deformation.
