Three-dimensional FEM Calculations of the Thermal-creep-stress in the Roller Compacted Concrete Gravity DAM with Face Wall

The concrete face wall can be adapted to rapid construction of the roller compacted concrete gravity dam,shorten construction period,reduced cost of construction formwork.This paper calculates thermal-creep-stress in the roller compacted gravity dam with face wall and without face wall by using creep theory,finite element theory and ANSYS software.The main conclusions are the thermal creep stresses patterns of two kinds of plans corresponds to ordinary rules,and it is reasonable,the face wall may appear cracks because of tensile stresses in it and the certain measures should be adopced.The calculation results have certain application values in engineering.
