土石混合体渗透性能的试坑双环注水试验研究
In-situ Double-Ring Infiltration Test of Soil-Rock Mixture
摘要
Abstract
For a landslide made up of soil-rock mixture near the dam of a large hydropower station in southwest China, in-situ infiltration tests were carried out by using improved double-ring infiltrometer. Four points at different places in the sliding body and six points in the sliding zone were tested respectively. The research indicated that the infiltration rate of soil-rock mixture was quite large and was close to that of non-cohesive coarse-grained soil. Meanwhile, the average infiltration rate in sliding body was 3-4 times larger than that in the slide zone. Indoor granulo-metric test on the soil of sliding body and sliding zone indicated that the content, density, particle shape and source of soil with diameter less than 5 mm are the main causes of infiltration rate difference.关键词
