摘　　要：江苏省盐城市紧邻东部沿海,区域内多滨海相沉积地质,影响工程建设的土体为第四纪松散沉积物,土质较软弱。该地区水工构筑物常采用复合地基对土体进行处理,但由于局部土质差异,容易出现结构物不均匀沉降,致使底板裂缝等影响结构质量的现象。文章根据盐城市城东水厂扩建工程的施工实践,对构筑物工后不均匀沉降的处理方案进行简要阐述。Yancheng,a city of Jiangsu Province,is located next to east coast of China.There are sedimentations of littoral facies which turn soil for construction into quaternary loose sediment,thus the soil condition is deteriorating.More often than not,hydraulic structures in Yancheng adopt the treatment of composite foundation.However,because the quality of soil varies,structures tend to fall into unequal settlement,which further leads to quality problems such as backplane cracks.Based on the analysis of the practical construction of the waterworks in the east of Yancheng,this study aims to make an elaboration on the treatment of hydraulic structure＇s unequal settlement after construction.
