【摘要】 本文针对长方形基坑井群降水采用等距布置井距或凭经验排列造成降水效果欠佳,排水耗能增加这一实际问题,以干扰井群计算理论为依据,建立基坑各不利点的干扰降深方程,提出了确定最佳井距的算法,此法使基坑降水的排水量减少3%,排水耗能降低9%.更多还原

【Abstract】 Aimed at the practical problems such as deficient effect of dewatering or increase of energy consumption by drainage, caused by adopting equal distance arrangement ofwells or empirical arrangement indewatering by well group in rectangular foundation pit. Based on the computation theory of interferenced well group, it establishes the interferenced drawdown equations at the unfavourable points of the foundation pit. It presents the computation method to determine the optimum spacing of wells. This method makes the discharge of foundation pit dewatering diminish by 3%, the drainage energy consumption diminish by 9%.更多还原
