摘　　要：对石梁河新建泄洪水闸闸墩整体结构混凝土温度场和徐变应力场的有限单元法多工况仿真计算 ,分析研究了裂缝成因 ,基本上弄清了闸墩混凝土温度变形、混凝土自身体积变形与干缩变形和基础底板的约束是裂缝产生的主要原因。就此 。For studying on the causes for cracks on the new_built sluice pier on Shiliang river, numerical simulations under various operation conditions are done by way of finite element method for the temperature and creep stress fields of the entire block structure. The thermal deformation, self_volumetric deformation and drying_shrinkage deformation, as well as the restriction of the concrete slab foundation are determined as the key causes for cracks. On this basis, some suggestions for anti_crack engineering measures are put forward in this paper.
