| 摘 要： | 成都平原部分地段出现了微承压地下水，经分析水质达到了国家饮用水标准。成都平原微承压地下水赋水岩层为第四系中一下更新统和上白垩统上部浅层风化带，第四系粘土层作为隔水层覆盖在含水层之上。在平原的周边丘陵地带，粘土层被风化剥蚀，含水层暴露，直接接受降水补给。地下水沿砂砾石、砂岩孔隙、泥岩溶隙溶洞和各种构造应力作用产生的裂隙运移，若遭遇断层切断切穿含水地层，便沿断层上升，在断层附近形成上升泉。

| Abstract: | The micro-confined groundwater was discovered in some parts of the Chengdu Plain. Examination of water quality indicates that the water quality reaches the national standards for drinking water. This article makes an approach to the occurrence and genetic mechanism for the micro-confined groundwater. The micro-confined fissures, forming ascending springs when migrating in faults. |
