摘 要: 基坑支护形式的确定受多方面因素的影响,许多工程根据经验进行设计,但实际效果却不理想。可以结合周边环境的变化,通过精确的监控监测,分析测斜管、应力计、水土压力计的监测数据,对设计进行优化。本文主要通过对武昌阅马场地下通道基坑支护监测数据的分析,提出了对红楼段的支护进行优化的方案,包括将基坑的两道支撑优化为一道支撑和改变支撑安装的方式和时间等,并对优化方案进行了跟踪监测。监测结果表明:优化方案在确保安全的基础上,达到了简化施工程序、节约施工费用的目的,对工程后期的施工提供了完整的数据参考。
关 键 词: 岩土工程;深基坑支护;监控监测;支护优化

Abstract: The form of foundation pit support is affected by many factors, and many projects are designed according to experience, however, the actual effect is not ideal. Combined with the changes of the surrounding environment, through accurate monitoring, the monitoring data of inclinometer tube, stress meter and water-soil pressure meter can be analyzed to optimize the design. This article puts forward the optimizing design scheme for the support of red building segment by analyzing the monitoring data of foundation pit support of Yuemachang underground passage. The scheme contains optimizing two layers of support to one layer of support, changing the way and time of support installation, and the track monitoring has been made on it. The monitoring results indicate that on the basis of ensuring safety, the optimization scheme achieves the goal of simplifying the construction procedure and saving the construction cost, it can provide a complete data reference to later construction.
Key words: geotechnical engineering; deep foundation pit support; monitoring and controlling; support optimization
