管井法和井点法是常用于深基坑降排水的人工降低地下水方法,现已用在南水北调渠道基坑降排水中。文章以南水北调某渠道工程基坑开挖为例,采用人工降低地下水方法进行降排水方案设计并分析估算其降排水费用,通过资源投入进行工程量的对比,进行了多方案优选,确定了经济合理的降排水方案,为工程设计提供理论依据。
Tube well method and well point method is commonly used in deep foundation pit drainage to reduce artificial groundwater method, is now used in the drainage channel of the South-North Water Diversion. Taking the foundation pit excavation of a channel project of South-to-North Water Diversion as an example, the scheme of reducing drainage by artificially lowering groundwater is designed and analyzed to estimate the cost of water drainage and drainage. By comparing the quantities of projects with resources input, a multi-program optimization is conducted to determine the economic rationality Of the drainage program, to provide a theoretical basis for engineering design.
