摘要
如何有效检测碾压混凝土坝的透水率一直是人们探讨的课题。湖南莽山水库大坝全断面主体为碾压混凝土坝,在大坝钻孔取芯压水试验中,改进压水系统及操作工艺,稳定可靠地获取了透水率;并开展碾压混凝土透水率、不利断口试验成果的相关分析,准确评定了碾压混凝土的质量及渗透状态。论文研究成果可供同类工程及相关试验参考。
How to effectively test the permeability of RCC dam is a topic people have always been discussing.The Mangshan reservoir dam in Hunan Province is RCC dam.In the the water pressuring test on the entire main RCC dam,the water pressure system and operation technology were improved,and the permeability rate was obtained.In addition,the test results of water permeability rate and adverse fracture test of RCC were analyzed,and the qual⁃ity and permeability state of RCC were accurately evaluated.The test results can be used as reference for similar projects and related tests.
