| 摘 要： | 高速公路桥头路段由于不均匀沉降带来的问题一直困扰着软土地基高速公路的建设,怎样使得桥头路段的地基处理方式既可以达到沉降控制的目的又可以达到节约建设经费的目的,是桥头路段软基处理的一个难点。基于某高速公路桥头路段现场沉降观测资料针对塑料排水板、水泥搅拌桩、塑料套管桩和预应力管桩处理方式,分别分析了处理深度6,8,13和27m的加固效果,结合每种处理方式在工程中的适用范围和每平方米造价,总结出一定处理深度范围内的桥头路段采用某一种处理方式能够达到加固效果和经济效果。

| Abstract: | The differential settlement of freeway bridge transitional belt is always a problem that influence the construction of freeway on soft foundation.Meanwhile,it is very difficult to solve the pre-problem and save money.Therefore,the effect of reinforcement is investigated in terms of the settlement data from the in-situ tests on a freeway bridge transitional belt.The data comes from several foundation treatment methods and several treatment depths on a freeway bridge transitional belt.Different methods are pl... |
