减少塑料排水板回带率的研究

摘要

回带是塑料排水板施工过程中最常见也是最难解决的问题，为查明回带原因，减少塑料排水板回带，结合工程实例，通过现场观察、数据收集，对比分析，总结出了4种适用于不同土质的减少回带的施工措施，为今后类似软基处理工程塑料排水板施工提供技术参考。%Back-drawing of drain is the most common and difficult problem in the construction of plastic drainage sheets. In order to find out the reasons for back-drawing of drain and reduce the back-drawing of plastic drainage sheets,this pa-per,combined with the engineering examples,summarizes four construction measures applied to different soils to reduce the back-drawing of drain by means of field observation,data collection and comparative analysis,which provides technical ref-erences to soft foundation treatment project for the future similar plastic drainage sheets construction.
