桩—网复合地基是一种新型的地基处理方式 ,尤其适合在天然软土地基上快速建造路堤或堤坝类构筑物 ,但目前国内外均没有合适的计算其工后沉降量的方法。路基沉降观测曲线包含了“网—桩—土”体系共同作用的丰富而全面的信息 ,以此为基础 ,考虑桩—网复合地基的具体情况 ,推导了三点法计算工后沉降量的公式 ,该公式简单实用 ,计算精度满足工程要求
Pile-net composite foundation is a new type of foundation treatment, which is especially suitable for rapid construction of embankment or embankment structures on natural soft soil foundation. However, there is no suitable method for calculating post-construction settlement at home and abroad. The embankment subsidence observation curve contains rich and comprehensive information about the interaction of “net-pile-soil” system. Based on this, considering the specific conditions of pile-net composite foundation, the formula of three-point method for calculating post-construction settlement is derived , The formula is simple and practical, the calculation accuracy to meet the engineering requirements
