贵阳西郊三桥地下水降落漏斗是贵阳地区边界条件明显，开采井密集，开采量大且较稳定的典型漏斗。在漏斗区域内地下水开采环境动态方面已作过较深人的研究，但对漏斗范围内地下水资源开采后是否会产生枯竭（疏于）的问题，已引起有关专家的关注。本文对漏斗区域内地下水资源量进行了评价。采用极限平衡的方法着重讨论了漏斗区域地下水开采量与漏斗中心最大水位降深（埋深）的关系，并用获取的量化指标判定了漏斗区域内地下水资源开采条件下的极限疏干状态。本文对于因过量开采地下水而造成的不良地质环境问题及资源管理方面有一定意义。
Groundwater landing funnel in the third bridge in the western suburbs of Guiyang is a typical funnel with obvious boundary conditions, intensive exploitation, large extraction and stable in Guiyang. Deep research has been done on the dynamics of groundwater exploitation in the funnel area. However, concerns about whether the depletion (neglect) of groundwater resources within the funnel area will have caused concern from the experts concerned. This paper evaluates the amount of groundwater resources in the funnel area. By using the method of limit equilibrium, the relationship between groundwater exploitation in the funnel area and the maximum water depth (depth) at the center of the funnel was discussed. The quantitative analysis index was used to determine the limit state of groundwater exploitation in the funnel area. This article is of some significance for the adverse geo-environmental problems and resource management caused by over-exploitation of groundwater.
