摘要
对市区软土地基道路的修筑难点进行了总结,梳理了因为施工方式不当引发的市区道路灾害类型,并就软土地基的特点给出了几种常见的处理方法,如土层灌浆法、粉煤灰碎石桩法和排水固结法,并结合工程实例重点研究了强夯法和高压旋喷桩加固软土路基的技术的特点和施工时的注意事项。
This paper summarizes the construction difficulties of urban soft soil foundation roads, sorts out the types of urban road disasters caused by improper construction methods, and gives several common treatment methods according to the characteristics of soft soil foundation, such as soil grouting method, fly ash gravel pile method and drainage consolidation method. Combined with engineering examples, the technical characteristics of dynamic compaction method and high pressure jet grouting pile for strengthening soft soil subgrade and the matters needing attention during construction are emphatically studied.
