山东文登抽水蓄能电站在探洞开挖至400m处,遇到断层带,并发生涌水问题,造成部分洞段出现塌方。涌水问题必定影响水资源均衡,考虑到探洞前方有两家矿泉水水厂,探洞因此停止施工。本文应用MODFLOW软件对该工程进行模拟研究,结合研究区的工程特性,通过建模、概化与计算,模拟了探洞开挖引起的涌水和地下水均衡问题,得出的模拟计算结果较为合理,为解决工程问题提供了强有力的依据,保证了探洞施工的顺利进行。说明MODFLOW在使用恰当的情况下,可以很好地模拟裂隙介质中地下水水流问题。
Shandong Wendeng pumped storage power station excavation to 400m Department, met the fault zone, and the problem of water gushing, resulting in the collapse of some cave sections. The problem of gushing water will inevitably affect the balance of water resources. Due to the fact that there are two mineral water plants in front of the exploration hole, the caverns will stop construction. In this paper, MODFLOW software is used to simulate the project. Based on the engineering characteristics of the study area, the problems of gushing water and groundwater balance caused by caving are simulated through modeling, generalization and calculation. The simulation results are reasonable Solve the engineering problems provide a strong basis to ensure the smooth caving construction. It indicates that MODFLOW can simulate groundwater flow in fractured media well when it is used properly.
