Abstract
Based on theories of finite element method, universal software ANSYS, by use of common software ANSYS as a platform, the influence degrees of transient temperature load and reservoir water load on arch dam stress are analyzed and computed. The result indicates that when the water level is same, the maximum tensile stress on arch dam has a close correlation with the variation of temperature, and the sensitivity of maximum tensile stress of arch dam for water temperature is higher than air temperature. The maximum tensile stress on arch dam does not correlate well with reservoir water level changes when the temperature is same. Through the non-dimensional processing on influencing factors which are temperature load and reservoir water level, the sensitivity of maximum tensile stress on arch dam for reservoir water pressure is higher than temperature load.
