| 摘 要： | 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中堤或堤坝类构筑物,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。

| Abstract: | Pile net composite foundation is a new type ground disposal method, especial for quick construction of embankment and dam on natural ground. However, there is not a proper calculating method for its residual settlement at home and abroad. The embankment settlement observation curve contains rich and overall information of "net pile soil" system action together. Based on this and the specific situation of pile net composite foundation, a "three point method" calculation formula of residual settlement is established. The formula is brief and practical. Its precision can satisfy engineering requirement. |
