高压旋喷桩在软土地基加固中的应用

Application of high-pressure rotary jetting pile in reinforcing soft soil foundation

根据对沪宁高速公路某桥桥头软土地基不均匀沉降进行的加固处理,分析了高压旋喷加固方法处理软土地基的可行性。经过通车后的使用,加固效果明显,可以应用于已建高速公路的路基加固工程。

Based on the reinforcing treatment practice of the uneven subsidence soft foundations for a certain bridge tower in Nanjing to Shanghai Expressway, the authors analyzed the feasibility of reinforcing the soft foundation by high-pressure rotary jetting, and it is concluded the reinforcing effect was evident when the bridge was open to traffic, and it was served as a reference for the reinforcing of the built road foundations.
