摘要
本文用静、动态分析方法,对土坝塑膜防渗后的灌溉和防洪效益进行了定量分析,为上坝塑膜防渗的经济效益作出了较为明确的量化评价。
In this article we have analysed quantitatively the gain of irrigation benefit and thebenefit in terms of flood control effectiveness after taking the seepage control measure withplastic membrane, by means of static and dynamic analysis; a more definite quantitative evaluation of economic benefit is given on seepage control measure of dams with plastic membrane.
