基于目标函数法的深基坑降排水优化设计

Deep Foundation Pit Dewatering and Drainage Design Optimization Based on Objective Function Method

以某工程为例,采用基坑管井降水设计方法设计得到了46口井的布置方案。以管井降水法求得的抽水量为初始参数,增加安全性约束条件,再利用目标函数法对降水井进行优化设计,优化后的设计方案减少了5口井。在满足设计需要的条件下,体现了目标函数法的优越性。

By means of project cases. 46 well of the well precipitation is obtained based on underground hydrodynamics. In pumping well point precipitation method of initial parameters obtained and increasing security constraints, using objective function method, the design of the dewatering well is optimized. 41 wells design project is obtained, thereby reducing 5 wells. In the condition of meeting the design needs, the objective function reflects its superiority.
