射阳河闸位于江苏省射阳县,全长412公尺,是江苏省目前最大的挡潮闸。闸基有10公尺厚的高压缩性软土层(a=0.062)。初步设计时,按以往习用的方法计算所得的沉陷量都在20公分以上,因此不得不考虑采用樁基。后经苏联地质专家建议可以采用天然地基,因此我室检查了过去各闸计算沉陷量偏大的原因,提出了回弹再压缩 Sheyang River Gate is located in Sheyang County, Jiangsu Province, a total length of 412 meters, is currently the largest tidal flats in Jiangsu Province. The gate base has a 10-cm-thick, highly compressible soft soil layer (a = 0.062). The initial design, according to the conventional methods used to calculate the settlement of 20 cm above, so have to consider the use of pile. After the Soviet Union geology experts suggested that the natural foundation can be used, so I check the room gate in the past calculated the cause of the settlement is too large, the proposed rebound compression
