Discussion on Key Technology for Soft Soil Subgrade Widening Highway Engineering Construction
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.
