摘要
在巨厚的承压含水层中,如何进行阻隔与减压降水一体化设计,探讨阻隔设计与减压降水二者之间的相互关系,研究阻隔与减压降水后坑外的水位降及影响范围,确定有关参数的相关性,通过回归分析重新修正并提出了综合考虑多因素耦合影响的坑外水位及影响范围计算公式,同时分析阻隔设计下坑外水位降的漏斗曲线方程,重点分析阻隔设计发挥的微扰动影响系数β,为降水与阻隔一体化设计提供指导参数。
In the confined aquifer of the thick,how to cut off and decompression precipitation integration design,explore the blocking design and stress the relationship between rainfall,cut off and the water level drop and influence of outside decompression precipitation Houkeng range,determine the correlation of the parameters,through the regression analysis to the correction and put forward a comprehensive consideration multi-factors coupling influence of formula of the pit water level and its influence scope,at the same time analysis block design outside the pit water level drop funnel curve equation,focuses on analyzing block design of micro disturbance influence coefficient beta,integrated design provides guidance for precipitation and block parameters.
