摘要

摘要: 介绍了一种利用BOTDA分布式光纤传感技术,监测地下连续墙在基坑开挖过程中受力变形过程的方法。通过在地下连续墙钢筋和H型钢上布设分布式光纤传感器,使之能够在基坑开挖过程中自动获取桩身的应变、弯矩、挠度等数据;采用双线的测量方法,具有温度自补偿的能力。

Abstract: The monitoring method for deformation force of continuous concrete wall during the excavation processs of a foundation pit is introduced by using the BOTDA distributed optical fiber sensing technology. Through the distributed optical fiber on the continuous concrete wall of steel and H steel, this technology can automatically acquire the data of strain, bending moment, deflection of piles during the excavation process. The monitoring method adopts double-line measurement and has the capability to self temperature compensation.
