| 摘 要： | 石河子某基坑设计水位降深为3.8 m,用"大井法"计算基坑涌水量,需布置19眼降水井。为准确计算基坑涌水量,利用Modflow软件建立了基坑降水模型,并用水位观测资料率定了模型。利用模型对基坑内各节点的水位降深进行了计算,通过不断的调整降水井布置方案,用17眼降水井,就使整个基坑水位达到了设计降深,且在基坑各部位水位降幅分布较均匀。与原方案相比,减少了2眼降水井,达到了优化设计、节约投资的目的。

| Abstract: | In Shihhotze the water table of certain foundation pit drawdown is 3.8 m.To use ＂dug well method＂ to calculate the volume of water seeping in foundation pit,19 wells need to be arranged.To exactly calculate water inflow of foundation pit,it is required to set up model of foundation pit dewatering by Modflow software,and use observation materials of water table calibration model.Meanwhile calculating water table drawdown of all nodes within the foundation pit by model and adjusting of layout program of dewatering well,water tables reach the design depth of the whole foundation pit with 17 dewatering wells,and the water table declines in various parts of foundation pit.Compared with former scheme,2 dewatering wells are decreased which achieves the goal of optimal design,and saves investments. |
