岩溶地区某学校基坑工程设计实践

Design Practice of Foundation Pit Engineering in a School in Karst Area

以惠州市岩溶地区某学校的基坑工程为例,分析工程特点与难点,并阐述在基坑工程的设计过程中,由于受现场地质条件和施工情况的影响,分别制定“单排桩+预应力锚索”、“放坡+土钉墙”的支护方案。结果表明:基坑支护设计实施效果良好,达到了预期的目标,很好地保护了周边环境,供类似项目借鉴。

Taking the foundation pit project of a school in the karst area of Huizhou City as an ex‐ample,the characteristics and difficulties of the project were analyzed.Due to the influence of site geological conditions and construction conditions,the supporting schemes of"single row pile+prestressed anchor cable"and"slope release+soil nailing wall"were formulated in the design process of the foundation pit project.The results demonstrate that the implementation effect of the foundation pit support design is excellent.The anticipated goal was achieved,and the surrounding environment was effectively protected.This can serve as a reference for similar projects.
