地下机械停车库基坑支护方案选型探析

Analysis on selection of supporting scheme for foundation pit of mechanical underground parking garage

随着城市用地愈发紧张,地下机械停车库逐渐成为解决城市机动车停车问题的重要方式。针对地下机械停车库深基坑开挖深度大、面积小、地质条件及周边环境复杂等特点,以福州某地下机械停车库为例,探讨该基坑的支护方案选型,并确定最终方案。基坑施工过程及监测结果表明,该基坑安全稳定,对周边环境影响较小。

With the shortage of urban land, mechanical underground parking has become an important way to solve the problem of motor vehicle parking.This kind of deep foundation pit possesses characteristics such as deep excavation, small area, complex geological conditions and surrounding environment.Based on the engineering of a mechanical underground parking garage in Fuzhou,the selection of supporting scheme for foundation pit is discussesed and supporting scheme is determined in the paper.The construction process and monitoring results of the foundation pit show that the foundation pit is safe and has little influence on the surrounding environment.
