摘要
在城市高层和大规模建筑的基坑开挖过程中,建立基坑支护和周围环境的变形监测系统不仅是施工安全要求,也是周边环境和居民安全保障的要求。全站仪和测斜仪是目前基坑开挖监测中较为常用的仪器。本文通过对全站仪和测斜仪的观测值的误差分析和工程应用比较,分析基坑边坡位移监测中两种仪器观测值的精度和可靠性,以及在不同地质条件的基坑开挖工程中的适用性。
In urban area, during the process of foundation pit excavation for high-rise building and large-scale construction, safety and security of construction is required for surrounding buildings and inhabitants. Therefore, to establish the foundation pit supporting and the surrounding environment monitoring system become very necessary. Electronic total station and inclinometer have been commonly used in monitoring deformations of foundation pit excavation. The observation accuracy and reliability of the two instruments in foundation pit slope displacement monitoring, and their applicability in excavation at different geological conditions are analyzed in this paper through comparing their observation errors and their applications.
