| 摘 要： | 本文提出一种确定碾压混凝土渗透系数与抗渗标号间关系的思路和方法,并在高压多功能渗透仪上进行碾压混凝土大量芯样的抗渗试验和渗透试验,试验芯样均取自国内某碾压混凝土坝,基于试验成果,建立碾压混凝土渗透系数与初渗压力(芯样表面开始出现渗水时的水压力)间的相关关系,根据抗渗标号的定义,给出碾压混凝土渗透系数与抗渗标号间的初步关系,为碾压混凝土渗透系数与抗渗标号的换算提供参考依据。

| Abstract: | A method used to determine the relationship between permeability coefficient and impermeability mark of Roller Compacted Concrete(RCC) is presented in this paper.Impermeability test and seepage test for lots of RCC samples are engaged with a high-pressure and multifunctional permeameter.All the RCC samples are obtained from a Roller Compacted Concrete Dam(RCCD).Based on the test results,correlation between permeability coefficient and initial seepage pressure is established. According to the definition of impermeability mark,preliminary relationship between permeability coefficient and impermeability mark is obtained.The research achievements provide the reference for the conversion between permeability coefficient and impermeability mark of RCC. |
