堤防工程防渗加固设计采用防渗墙方案较为普遍 ,新型机械设备的使用使防渗墙施工更为快捷 ,但大型机械设备作用于存在一定工程缺陷的堤身可能导致堤身出现裂缝。针对同马大堤堤身防渗墙施工过程中出现的裂缝 ,分析裂缝产生原因 ,介绍了处理措施。 The seepage prevention and reinforcement design of embankment project is more common with the seepage prevention wall scheme. The use of new type of mechanical equipment makes the construction of cutoff wall more rapid, but the large mechanical equipment acting on the embankment with certain engineering defects may cause cracks in the dike. Aiming at the cracks that occurred in the construction process of the cutoff wall of Dike Embankment, the causes of cracks were analyzed and the treatment measures were introduced.
