摘    要:采用塑料排水板堆载预压法对某软土路基工程进行处理,对路基变形及孔隙水压力等进行了严密观测;同时采取浅层沉降监测、深层沉降监测、孔隙水压力监测、地下水位观测等手段,以及地表沉降、孔隙水压力等变化规律,推算出预压荷载下的最终沉降量和固结度,深入分析塑料排水板堆载预压软土地基处理方法的加固效果。分析结果表明,该方法能有效地加快软基的固结沉降,提高地基土的稳定性和承载力,可供软土地基处理设计与施工参考。

关 键 词:塑料排水板  软基处理  变形检测  固结度

Abstract:Plastic drainage plate preloading method is adopted for the soft soil foundation treatment. The prepress process on the deformation and pore water pressure are closely observed. At the same time, the settlement and the degree of consolidation under the final pre-load pres- sure are calculated with the variation of the surface subsidence and pore water pressure by the shallow subsidence monitoring, deep subsid- ence monitoring, pore water pressure monitoring,groundwater and other means of observation. The plastic drainage plate preloadiug Reinfor- cing of soft soll treatment effect is deep analyzed. And the results show that the method can effectively accelerate the consolidation settlement of soft ground, improve soil stability and bearing capaclty,design and construction of treatment for soft reference.
Keywords:plastic drainage board  soft ground  deformation detection  degree of consolidation
