摘　　要：塑料排水板施工是软土地基处理质量控制难度最大的环节,实际施工中经常只根据感官判断是否合格。结合连云港某真空预压工程实例,总结排水板施工的各个环节的质量控制策略,并从技术角度对现场施工中遇到的质量问题及技术难点进行分析,提出塑料排水板施打深度的计算公式,以及板位偏差、垂直度、回带等问题在实际施工管理时的质量控制方法,为类似工程提供参考。The construction of prefabricated drain is the most difficult link in quality control of soft soil foundation treatment.In the actual construction,only the sensory is often used to judge whether the quality is qualified or not.Combining with a vacuum preloading in Lianyungang project,we summarize drainage board construction each link of quality control strategies,analyze the site construction quality problems and technical difficulties from a technical point,and propose the formula for calculating the laying depth of prefabricated drain and the method for controlling the deviation of prefabricated drain position,verticality and return of prefabricated drain in actual construction management.The results can provide references for the similar projects.
