摘　　要：水工墩墙结构广泛分布于水闸、涵洞、挡土墙等水利工程中,水工墩墙开裂已成为水利工程建设的一个通病。在对水工墩墙结构裂缝的形式、成因进行详细分析的基础上,提出从混凝土材料、结构布置形式、施工方法与工艺等方面防止产生裂缝的措施,这些措施对解决其他结构形式裂缝也具有一定的参考价值。Hydraulic pier structures are widely used in the construction of sluices,culverts and earth-retaining walls. Cracking of hydraulic piers becomes very common in hydraulic project construction. In order to prevent the happening of cracking,measures such as improving concrete materials,structure layout and construction method and techniques are put forward,on the basis of making a detailed analysis of forms and reasons of cracking. These measures also have reference value for solving cracking problems of other structures.
