Dynamic precipitation control method for foundation pit
The invention provides a dynamic precipitation control method for a foundation pit, which comprises the following steps of: obtaining and analyzing data through water pumping of a test well and a precipitation test, establishing an underground water conceptual model and a numerical model, calibrating water pumping test data by using the underground water numerical model, and finally, simulating and optimizing precipitation design through modeling. The underground water level is controlled within the range capable of meeting the construction requirement according to the thought of step-by-step dewatering and on-demand dewatering in the dewatering process, the dewatering depth and the operation number of dewatering wells are reduced as much as possible, and compared with a large-scale heavy dewatering process, the operation number of the dewatering wells is greatly reduced, economical efficiency is good, and energy conservation and environmental protection are achieved; the method is particularly suitable for large foundation pit dewatering in coastal strong permeable areas.
本发明提供一种基坑动态降水控制方法，通过试验井抽水、降水试验得到数据并分析，进行地下水概念模型和数值模型的建立，再利用地下水数值模型来校准抽水试验数据，最后通过建模仿真优化降水设计。降水过程中按照分步降水、按需降水的思路，将地下水位控制在能够满足施工要求的范围内，并尽可能减少降深与降水井运营数量，与大规模强降水工艺相比，大大降低了降水井运行数量，经济性好，节能环保；特别适用于临海强透水区域的大型基坑降水。
