摘要
长春市北西或北北西向张扭性断裂或断裂带是客观存在，它对长春市深部地下水循环与赋存起控制作用，是深部基岩裂隙水的主要导水通道，且大都为富水带。原北东向压扭性断裂或断裂带起阻水作用，二者相得益彰。笔者于长春北郊贫水区，利用这一新理论，在水文地质调查基础上，结合多种水文物探手段布孔凿井，打出一口水量丰富的优质矿泉水井，进而验证了北西向富水说，提出了长春市深部地下水赋存规律的新认识。此说不但对长春市供水有实际意义，而且对指导长──哈经济区城镇开发地下水资源也有重要的推广价值。
There are NW or NNW tenso-shear fractures or fractural zones in Changchun City.They contrl deep groundwater circulation and occurrence,being the main diversion passagesof deep bedrock fracture water,in which most aqtiifer beds are formed in this area. The origi-nal NE tenso-shear fractures or fractural zoi1es pltig;groundwater flow. By using this discov-ery,on the basis of hydrogeological investigation with combining different hydrogeophysicalapproaches,and high water yield is completed in the northern suburb of Changchtin City. So,rich groundwater in the NW towards of this area is verified and a new cognition on the occur-rence law of deep groundwater in Changchun City is proposed.This method not only haspractical significance for water application in Changchun City,but also has an important val-ue to developing groundwater resources in Changchun-Harbin economic developing area.
