Due to the construction of the Three Gorges Dam impoundment project and the Baihetan Hydropower Station in China，the water level of the upstream of the dam varies more dramatically.As a result，the frame height of the high-pile framed wharf increases，and the size of the structural section of the wharf increases accordingly，which further leads to a larger influence of temperature on the structure.By investigating the Gele Tourist Center wharf project，which is a first-phase project of the Dongchuan Port construction project in Yunnan Province，this paper develops a concrete high-pile framed wharf model under temperature stress by the finite-element software ANSYS.Furthermore，it examines the adverse effect of temperature change on the structure and the influence of horizontal braces on the temperature effect on the structure.The results show that after seasonal warming，the most unfavorable position in the structure is at the lower part of the upper beam and the roof in the sense that the tensile stress in this area is large，which may lead to the tensile cracking failure of the concrete.The most unfavorable position in the structure is in the bottom beam after seasonal cooling.Placing horizontal braces in the structure can effectively reduce its temperature stress.
