摘要
随着可持续发展战略的深化,隧道工程所引起的地下水环境问题越来越突出。简要介绍了裂隙岩体渗流特征、渗流模型及渗流计算原理,采用等效连续介质渗流模型模拟裂隙岩体隧道渗流规律并定量评价地下水资源流失量,为提高模型拟真性,在模型中考虑了裂隙岩体的非均质性和各向异性,并应用于实际工程中进行了隧道运营期间的地下水流失量计算,为减小隧道施工地下水资源流失提供技术支持。
With the deepening of sustainable development strategy,groundwater environmental problems caused by tunnel projects are becoming more and more outstanding.This paper briefly introduced the seepage flow characteristic of fracture rock,seepage models and seepage calculation by using the theory of equivalent continuum percolation model to simulate the fractured rock mass tunnel seepage rule and quantitative evaluation of groundwater resources loss.In order to increase the model fidelity,the author considers the nonhomogeneous and anisotropic characteristics of fractured rock.The flow model is used in tunnel engineering project for the loss of groundwater resources forecast,which provides technical support for decreasing loss of groundwater resources.
