| Abstract: | In order to study the feasibility of the automatic fixed inclinometer in the monitoring of the horizontal displacement of the deep underground diaphragm wall,the automatic measuring hole 1 with a spacing of 1 m and the artificial hole CX8 measured at 0.5 m were arranged.Comparative analysis and matching analysis of on-site construction conditions showed that the data of a single sensor in automatic monitoring showed an overall pattern of first negative,then negative and positive,and then all positive from the orifice to the bottom of the hole,and the maximum horizontal cumulative displacement of the measuring point had always been near the excavation surface to reach maximum.Both manual monitoring and automatic monitoring of the deep horizontal cumulative displacement curve could timely and accurately reflect the horizontal displacement of the foundation pit caused by various working conditions.It showed that the automatic monitoring could better reflect the deformation of the deep horizontal displacement,and then verified the feasibility of the fixed inclinometer in the deep horizontal displacement monitoring of the foundation pit. |
