塑料防护排水板纵向通水能力测试技术研究塑料防护排水板纵向通水能力测试技术研究张鹏程(上海勘测设计研究院，上海200434)【摘要】通过对塑料防护排水板纵向通水能力测试技术研究，并对试验结果进行分析，指出：针对软土地基加固用塑料排水带的纵向通水量测试方法不适用于塑料防护排水板的相关试验；塑料防护排水板的纵向通水能力测试可以闭孔泡沫橡胶加压方式，在150kPa法向压力和0．1水力梯度条件下进行；其纵向通水能力与其凹凸高度呈正比关系。【关键词】塑料防护排水板；通水能力；测试中图分类号：TV523文献标志码：A文章编号：1005-4774(2014)05-0033-04StudyofVerticalWaterFluxCapacityTestingTechnologyinPlasticProtectiveDrainageBoardZHANGPeng—cheng(ShanghaiInvestigation，Design&ResearchInstitute，Shanghai，200434，China)Abstract：Verticalwaterfluxcapacitytestingtechnologyofplasticprotectivedrainageboardisstudied，andthenthetestresultsareanalyzed．Thefollowsareproposed：verticalwaterfluxcapacitytestingmethodaimingatplasticdrainagebeltforreinforcingsoftoilfoundationisnotapplicabletorelatedtestsofplasticprotectivedrainageboard．Verticalwaterfluxcapacitytestingofplasticprotectivedrainageboardcanbeconductedthroughclosed—cellfoamrubbercompressionmodeundertheconditionof150kPanormalpressureandhydraulicgradient0．1．Theverticalwaterfluxcapacityhasproportionalrelationshipwithi
