深厚软土地基综合处理技术试验研究

Experimental research on comprehensive treatment techniques for deep and thick soft ground

根据深厚软土地基的特性及地基处理要求,结合碎石垫层、轻型井点排水固结、强夯法、振冲碎石桩4种地基处理方法的综合处理技术优势,开展地基综合处理技术试验研究。对处理过程中地下水及孔隙水压力等指标进行了细致的监测,并对处理前后的地基承载力进行对比分析,结果表明,该综合地基处理方法可弥补单一地基处理方式的缺点,能够有效提高地基承载力。本文可为后续的同类地基处理工程施工提供借鉴。

According to the characteristics of deep and thick soft soil ground and the requirements of ground treatment,combined with the comprehensive treatment technology advantages of the four foundation treatment methods of gravel cushion,light well point precipitation,dynamic compaction,and vibration‑replacement stone column,experimental research on comprehensive foundation treatment technology was conducted.The treatment process index such as groundwater,pore water pressure were carefully monitored,and the foundation bearing capacity before and after treatment was compared and analyzed.The results show that the comprehensive ground treatment method can make up for the shortcomings of a single ground treatment method,and can effectively improve the bearing capacity of ground.The article can provide a reference for subsequent construction of similar ground treatment projects.
