浅谈塑料排水板堆载预压法处理深厚软土路基

Elementary Discussion of Plastic Drainage Plate Surcharge Preloading Method to Treat Deep Soft Soil Subgrade

首先,介绍了塑料排水板堆载预压法处理深厚软土路基的设计。接着,阐述了堆载预压法的要素和原理,以及竖向排水体的设计要点;并通过工程实例,论述了塑料排水板和预压荷载的设计及地基固结度计算。计算结果表明:塑料排水板堆载预压法处理深厚软土路基具有良好的效果,而涂抹和井阻作用对土体固结的影响比较显著。

This paper introduces the design of plastic drainage plate surcharge method to treat the deep soft soil subgrade, sets forth the elements and the principle of surcharge preloading method and the design gist of vertical drainage body, and discusses the design of plastic drainage plate and preloading load as well as the calculation of subgrade consolidation degree by the engineering cases. The calculation results show that the plastic drainage plate surcharge preloading method to treat the deep soft soil subgrade has a good effect, but the influence of smearing and well resistance on the soil consolidation is more obvious.
