摘　　要：针对基坑降水方案确定过程中的计算问题,参考相关技术手册及资料,总结了其主要计算步骤。基于VB程序设计方法,编写可视化程序,实现不同井位、抽水量、井结构条件下,基坑范围内水位变化预报。结合北京某大厦基坑调查的实际数据,对基坑工程的降水方案进行了设计计算,获得了井点数量及间距、布井方式等对施工有指导意义的数据,同时,对人工降水对周围水环境的影响进行了预测。结果表明:通过人机交互系统,可方便快速地确定合理的降水实施方案,为安全施工提供可靠依据。Aiming at the calculation of establishing the scheme for foundation dewatering, the key steps have been summarized by the authors, basing on the related technical manual and reference. The visual program has been written with Visual Basic language. Making use of it, the changes of the water level in the foundation area can be predicted timely, in the condition of the different well locations, well construction, pumping rate and others. Based on the building pit survey data in Beijng, a dewatering scheme of foundation pit was designed, the amount and spacing of well were obtained, and Flow field of surrounding foundation pit was forecasted. The result shows that the dewatering scheme will be made quickly and reasonable by human-computer interaction, which will provide a reliable basis for the safe construction.
