Abstract: Using the inclinometer monitoring of a soft soil preloading treatment project in Jiangmen City,Guangdong Province as an example, this paper describes the components of the inclinometer monitoring system and summarizes the precautions in the process of monitoring, presents the plots of depthdisplacement curves, displacement ratetime curves.This paper also discusses the warning value of the inclinometer monitoring,and the phenomenon of the probe jumping from one groove to another groove during inclination monitoring, and the refloating measures for the inclinometer.

Key words: Preloading, Monitoring Techniques of Deep Lateral Movement, Curve of DisplacementDepth
