Application of automatic monitoring of horizontal displacement in deep foundation pits of intercity railways
Traditional horizontal displacement monitoring of deep foundation pit retaining structures usually uses inclinometers to manually collect data,which has disadvantages such as low monitoring frequency,slow data feedback,and susceptibility to external factors. This article introduced the working principle and composition of an online inclinometer system and elaborated on its application in monitoring the main foundation pit of an intercity railway station in Nanjing. The results show that the online inclinometer system can achieve automatic collection,transmission,and processing of monitoring data,provide real-time monitoring results,and draw deformation curves. The results can truly reflect the displacement of the foundation pit retaining structure,and the monitoring accuracy can meet the needs of construction. The deep horizontal cumulative displacement curves of manual monitoring points and online inclinometer monitoring points have a good correlation and can accurately and timely reflect the horizontal displacement of the foundation pit under different working conditions.
