随着水利基础设施的不断建设,江河湖海的堤防上兴建了很多穿堤建筑物,建筑物地基的处理及其与两侧堤身之间的连接段是否安全,直接关系着整个河道工程的成败。笔者通过工程实例,结合海门市东灶新河河道工程地质条件,对垫层法、强力夯实法、振动水冲法、桩基础及沉井基础等方法的主要优缺点进行分析,阐述了地基处理方法的选择,按照本工程实际情况,本次设计拟采用桩基础进行地基处理,并简要介绍了其设计和施工要点。
With the constant construction of water conservancy infrastructure, many embankments are built on the embankments of the rivers, lakes and seas. The handling of the foundations of the buildings and the connection between them and the embankments on both sides are safe and are directly related to the entire river course Success or failure. Based on the engineering examples and the engineering geological conditions of Dongzao New River, Haimen, the author analyzes the main advantages and disadvantages of the methods such as cushion method, powerful compaction method, vibrating water scouring method, pile foundation and caisson foundation, and expounds the foundation treatment According to the actual situation of this project, this design intends to use pile foundation for foundation treatment and briefly introduces its design and construction essentials.
