在确定供水井位时,必须考虑井位的岩性、构造、地貌、补给、径流、排泄、动态等条件,同时考虑供水钻孔在地下水运动的部位以及岩溶发育阶段,最后分析各影响因素间的组合关系。当有机地结合以上诸条件,或当有利条件不都具备,而能找出控水的主要矛盾,以解决所需水量、水质时,供水井的定位才较有把握。本文仅就上述诸因素中的构造条件,特别是点上的构造条件对钻孔富水的影响问题进行一些讨沦与分析,以期有效地确定供水井位目的。
In determining the water supply well position, we must consider the well location lithology, structure, geomorphology, recharge, runoff, drainage, dynamic conditions, taking into account the location of water supply drilling in the groundwater movement and karst development stage, the final analysis of the impact of various factors The combination of relations. When organic combination of the above conditions, or when favorable conditions are not available, but can find out the main contradiction between water control, in order to solve the required water, water quality, the positioning of the water supply well is more sure. In this paper, only some of the above factors in the structural conditions, especially the point of construction conditions on the impact of drilling rich water some discussion and analysis, in order to effectively determine the purpose of water supply wells.
