摘要
以微山湖二线船闸基坑降水计算为例,把地表水发育地区、含水层和隔水层互层交错的水文地质条件,近似为无限均质含水层。基坑降水时基坑降水与均质含水层、设定降深、长期稳定开采时地下水资源计算雷同,理想大井法适用于基坑涌水量估算。
：Set foundation pit precipitation in second line lock gate in Weishanhu lake as an example, surface water developing area, hydrogeological condition of water-bearing and water-resisting layer interbedded are approximated to boundless homogeneous water-bearing layer. Calculation of foundation pit precipitation is approximate with homogeneous water-bearing layer, designed precipitation depth, and underground water amount under long-time stable mining. Ideal large-well mehtod is suitable for calculationg discharge rate of foundation pit.
