摘要
通过对西安黄土梁洼地区进行基坑降水试验,用潜水完整井稳定流理论分析抽水试验过程,获得其水文地质参数,研究降水过程中渗透系数、基坑总出水量、降水影响半径等的变化特性,在此基础上计算、分析其水位降深和沉降变化规律,为西安地区的基坑降水设计与施工提供依据。
The paper undertakes the dewatering test of foundation pits at the loess Liangwa Area in Xi＇ an, analyzes the pumping test by the steady flow theory of the penetrating groundwater well, obtains its hydrogeology parameter, researches the change features for the penetrating coef- ficient, the total outflow runoff, and the dewatering affecting radius of the dewatering process, calculates and analyzes the changing law for the drawdown and settlement changes based on the previous aspects, so as to provide the reference for the design and construction of the dewatering at foundation pits in Xi＇an area.
