| 摘 要： | 随着城市建设的不断加大，地下空间开发程度越来越深，伴随着基坑的开挖越来越深，城市的扩展不可避免地对地下水的补给、径流、排泄条件产生影响，而水文地质条件的改变又反过来影响制约人类的活动，甚至引发工程安全问题。该文以济南某建设项目为例，通过水文地质勘查、地球物理勘探、水位动态模拟、地下水取样等手段，研究分析近年来该建设项目周边地下水补径排条件的改变对区域地下水位的影响，以及水文地质条件的变化对建设项目工程的制约。结果表明，由于地下工程开挖、大气降水、保泉政策等因素影响，地下构筑物的开挖阻断了唯一的排泄通道，该建设项目周边地下水渗流场发生变化，由此造成项目区周边地下水位大幅上升，超过前期设计的抗浮设防水位，并对地下构筑物产生了破坏。研究结果对周边类似建设项目的选址及地下空间的开挖具有一定的指导意义。

| Abstract: | Accompanying with continuous increase of urban construction, the development of underground space is getting deeper. Accompanying with the deeper excavation of the foundation pits, the city expansion will inevitably affect the recharge, runoff and discharge conditions of the groundwater. The change of hydrogeological conditions will in turn affect and restrict the activities of human beings, and even cause in engineering safety problems. Taking a construction project in Ji''nan city as an example. Due to the influences of underground engineering excavation, atmospheric precipitation, and spring protection policy, the excavation of underground structures blocked the only discharge channel, the groundwater seepage field around the construction project changed, resulting in a sharp rise in the groundwater level around the project area, of which exceeded the anti floating water level designed in the early stage, and damaged the underground structures. It will provide some references for site selection of similar construction projects and the excavation of underground space near the study area. |
