摘要
桥梁桩基除了承载力要求之外,对沉降变形还有诸多限制。随着交通量不断增长,拓宽工程也越来越多,桩基沉降变形的控制标准趋于严格。相比传统设计方法,将沉降变形作为桩基设计控制要素的桩基沉降控制方法更加适用。实例比较了多个桩基设计方案的技术经济性能,并进行了桩基参数对技术指标和经济指标的参数分析。
In addition to the requirements of bearing capacity of bridge pile,there are many restrictions on the settlement deformation.With the growing of traffic,more and more widening projects are put into practice,and the control standards of pile settlement deformation tend to be more strict.Compared with the traditional design methods,the Pile Settlement Control Method,which uses the settlement deformation as the control element for the pile design,is more applicable.The technical and the economic performance of multiple pile design schemes are compared with some examples,and the parameters of the foundation on technical index and economic index are conduced.
