摘要
结合某地铁站岩土工程勘察抽水试验的实践,介绍了采用抽水试验测定黄土层的渗透系数、影响半径的实例,提出了针对黄土地区综合渗透系数以及水位观测孔布设方法的建议,为黄土地区基坑降水提供借鉴。
In this paper, methods to measure the permeability coefficient and its radius of influence are introduced by a pumping test in loess area. A new method is proposed for the permeability coefficient in loess area and its arrangement of obser- vation wells. This work has some guidance for the excavation dewatering.
