【摘要】 基坑降水过程中由于多采用经验渗透系数,降水井布置不合理,直接影响基础及上部结构的施工。本文以太原市某电厂基坑降水为实例,通过抽水试验确定渗透系数,采用大口井方法确定基坑涌水量和基坑影响半径,制定合理的基坑降水及基坑支护和回灌技术方案,并推广该技术方案在在电力行业中的应用。更多还原

【Abstract】 Dewatering well set unreasonable because of using the experience hydraulic conductivity in the process of the dewatering,which has a direct effect on the construction of the foundation and superstructure.This paper takes the case of dewatering of a power plant in Taiyuan,obtain the hydraulic conductivity by pumping test,use large opening well method to ascertain the water inflow and radius of influence of the foundation pit,formulate reasonable plans for dewatering and recharge,and promote this plans in the application of the power industry.更多还原
