摘要
在公路建设领域,软土路基占据着重要地位。随着我国经济的持续发展,公众的交通需求不断增加,现有道路已无法充分满足需求,对现有道路进行加宽和改造势在必行。然而,在软土路基加宽过程中,面临着诸多挑战。文章以某高速公路软土路基加宽工程为研究对象,由于该工程采用了高压旋喷桩复合地基,并且有新建软土路基路段,因此文章主要分析高压旋喷桩复合地基施工技术与CFG桩施工技术的应用,以供参考。
In the field of highway construction,soft soil subgrade occupies an important position.With the continuous development of China's economy,the traffic demand of the public is increasing,and the existing roads can no longer fully meet the demand.Therefore,it is imperative to widen and transform existing roads.However,there are many challenges in the process of soft soil subgrade widening.This paper takes an expressway soft soil subgrade widening project as the research object.Because the project adopts high-pressure rotary jet grouting pile composite foundation and there are new soft soil subgrade sections,it mainly analyzes the application of high-pressure rotary jet grouting pile composite foundation construction technology and CFG pile construction technology for reference.
