| 摘 要： | 民乐山前平原新构造运动十分活跃 ,新第三纪以来的断裂构造 ,造成了盆地基底形态变化 ,从而导致区内地下水位由南向北随断裂带的分布 ,形成了多级跌水陡坎。断层上盘水位埋深一般在 10 0m左右 ,断层下盘水位埋深大于 150m。进一步查明区内基底构造 ,对寻找利于开采的浅埋地下水有着重要的指导意义

| Abstract: | Neotectonism of Minle piedmont alluvial plain is very active.The fault structure developed since Neogene leads to the changes of the shapes of Minle Basin basement.Consequently,the groundwater in the studied area is distributed as down water fall steps from south to north.Generally,the buried depth of the water level of hanging wall is about 100m,and that of footwall is over 150m. Studies show that clarifying the distribution of basement structure is of great significance for prospecting the shallow buried groundwater. |
