湖州地区大部分水工建筑物多建造在软粘土地基上,其持力层范围内主要有淤泥土、淤泥质粘土或淤泥质轻亚粘土,含水量高、空隙比大,压缩性大,抗剪强度低,透水性差,地基承载力低,只有50～75KN/m~2。为此,湖州市水电设计院以结构轻型和布局合理为原则,设计了大量的轻型水工建筑物。例如:蓬蓬洋闸站工程和沈家墩排涝站工程,其平面布局合理,结构型式轻巧,比较适合软土地基沉降变形,其综合经济效益十分显著。蓬蓬洋闸站工程位于湖州市百丈港圩区的最北端,设计具有以下特点:1.闸站共用翼墙、墩墙
Most of the hydraulic structures in Huzhou area are mostly built on the soft clay foundation. There are mainly silt, silty clay or silty light loam in the holding layer, with high water content, large void ratio, large compressibility, Shear strength is low, water permeability is poor, bearing capacity of foundation is low, only 50 ~ 75KN / m ~ 2. To this end, Huzhou Hydropower Design Institute with light structure and reasonable layout for the principle of designing a large number of light hydraulic structures. For example: Pung Peng ocean gate station project and Shenjiadun drainage station project, the plane layout is reasonable, lightweight structure, more suitable for soft ground settlement, the comprehensive economic benefits are significant. Peng Peng ocean gate station project is located in Huzhou City Baizhang port area of the northernmost tip, the design has the following characteristics: 1. gate share wing wall, pier wall
