关于道路软基创新处理方法的技术经济探讨

Further Discussion on Technology and Economy of Road Soft Subgrade Innovation Treatment Method

针对江汉平原软弱土层路基,且地下水位丰富的特点,在充分考虑施工周期的前提下采用先进专利技术高真空击密法处理。以黄冈大道路基处理为依托,采用井点降水后换填、水泥搅拌桩、高真空击密法对比分析后选择高真空击密法。并对此法处理后路基相关指标进行实测,实测数据结果和处理后管槽开挖情况均达到预期的目的,既控制了工程周期又节约工程投资值得推广。

According to the characteristics of weak soil subgradeand rich groundwaterinJianghan Plain,and on the premise of fully considering the construction period,the advanced patent technology of high vacuumtamping compaction method is adopted Based on the subgrade treatment of Huanggang avenue,the high vacuumtamping compaction method is adopted after comparison and analysis of the subgrade replacement method of the well point dewatering the cement mixing pile method and the high vacuumtamping compaction method.Relevant indexes of the subgrade processed by the high vacuumtampi ng compaction method are measured.The measured data and the excavation of the processed pipe groovesall achieve the expected purposes The adopted method not only controls the project cycle,but alsosaves the engineeringinvestment.Sothis method is worthy of popularization
