- Abstract
Horizontal displacement monitoring of pile is an important part of deep foundation pit monitoring. The foundation pit of a station of Chengdu Metro Line 13 is located in the green belt in the northeast direction of Chenglong Avenue, Jinjiang District. The overall geological condition is poor, and the safety level of the foundation pit is Level 1. In this paper, the horizontal displacement monitoring was carried out for a foundation pit in a station of Chengdu Metro to understands the deformation situation and trend of different depths of piles, so as to ensure the deformation monitoring of the surrounding environment and the key parts of the project itself during the excavation of the foundation pit and provide data support for the comprehensive monitoring of the construction process and the safety of the foundation pit. Regular measurement and drawing of pile horizontal displacement curve can directly reflect whether the soil around the foundation pit is safe and stable or not, and provide safety basis for subway construction. Through the analysis of monitoring data, the deformation of horizontal displacement of pile body was found small at both pile top and base, large in the pile middle, the horizontal displacement curve is like a bulge, and its variation trend is related to the surrounding surface settlement and the change of supporting axial force. The rules provided a reference for the similar deformation monitoring projects in the future.
