道桥施工中软土地基处理技术要点分析

Key Points Analysis of Soft Foundation Treatment Construction Technology in Road and Bridge Construction

软土地基以其较低的承载能力、较大的压缩性和变形性等特点,给工程建设带来许多挑战,如果处理不当,很容易引发工程质量问题,甚至出现工程事故。针对软土地基承载能力低、压缩性大、变形性强等特点,结合换填加固处理的实例,分析了排水固结、强夯处理、混合剂处理和换填加固4种常见的处理技术,阐述了这些技术在软土地基处理中的具体应用。研究表明,这些技术都能改善土体性质,提高地基的承载力和稳定性,进一步提高道路和桥梁建设的质量和水平。

Soft soil foundation,with its low bearing capacity,high compressibility and deformability,poses many challenges to engineering construction.If not handled properly,it can easily lead to engineering quality problems and even accidents.Based on the characteristics of low bearing capacity,high compressibility,and strong deformation of soft soil foundation,combined with examples of replacement and reinforcement treatment,four common treatment techniques are proposed:drainage consolidation,dynamic compaction treatment,mixture treatment,and replacement and reinforcement.The specific applications of these techniques in soft soil foundation treatment are elaborated.Research has shown that these technologies can improve soil properties,enhance the bearing capacity and stability of foundations,and further improve the quality and level of road and bridge construction.
