摘要
为了确定坝基土体的渗透系数及渗漏量,以东湖水库的工程地质勘察、试验资料为基础,通过室内试验、现场试验、经验公式与理论公式等多种方法计算土体的渗透系数,并分析计算结果之间的差异。结果表明,土体渗透系数应采用多种方法综合确定,才更能准确地估算坝基渗漏量。
For correctly deciding permeating coefficient and seepage quantity of dam base soil body, the paper is based on the datum of engineering geological prospecting and testing in Donghu Reservoir. Permeating coefficients of soil body are calculated by the several methods such as indoor experiment, site experiment, empirical and theoretical formulas, the differences of calculating results are analyzed. The results indicate that soil body permeating coefficient should be decided by several ways, which can more accurately estimate the amount of dam base seepage and serve for engineering design.
