Optimization Design Of Foundation Pit Dewatering Base On Target Function Method

Pit Dewatering as one of the important work of the foundation excavation, lower the groundwater levels, prevent the bottom of the pit uplift, and ensure the construct normally. The dewatering design decide the precipitation scheme’s success or failure.In practical engineering, the usual method used in dewatering design is relatively simple, but the reasonableness of the scheme is unsatisfactory,so, optimization of precipitation design is necessary.In this paper, some describes the theory and its method of foundation pit dewatering firstly,using the formula of steady flow to calculate,then establishing objective funetionand that make the foundation Pit’s total water inflow is minimum.using C#language to write A precipitation optimization program. Users can get optimized precipitation design based on after input the parameter.reference optimized precipitation design to adjust the well point and the length of the filter pipe, then use the program to optimize the calculation once more。 with the constantly optimization calculations, the Precipitation design will more reasonable。Use midas gts to simulate the optimized precipitation design, verify its precipitation effects,compare the difference between original precipitation design and optimized precipitation design。...
