全站仪深基坑开挖安全监测与分析

在深基坑开挖过程中,一项重要的任务就是对基坑及其周围影响带内的地物进行监测,以保证施工现场的安全和进度的顺利安排。在阐述开挖事故原因的基础上,通过讨论全站仪自由设站的计算方法,并结合极坐标测量空间坐标的原理,提出了应用时空变形过程线分析变形趋势的预测方法,这种方法能够满足基坑安全监测工程的精度要求,并且成本低,速度快,能够为现场安全评估和方案设计提供可靠的数据基础。

Safe Monitor and Analysis of Deep Excavation with Total Station

During the process of deep excavation digging,it is an important task to monitor the excavation and affected building to make sure the spot's safety and go on wheels with the schedule.In this article some causation of slip and the calculation methods of freely setting station are first discussed,and then combined with the theory of polar coordinates a forecast method through distortion course curve analysis is put forward.The method with its low cost and speediness,can satisfy the precision requirement and provide the base data for safe evaluating and designing.
