Abstract: To study the post construction stability and the deformation of a reinforced building slope, this paper presents a history of the surface deformation monitoring of a building slope in Guizhou. By using the site investigation data, the surface movement of the building slope was monitored, and the stability of the slope was analyzed from May of 1028 to February 2019. The results indicate that, ①within the monitoring period, the slope movement has a trend of stabilized, rapid and then stabilized movement. The most rapid movement was observed in the period between May and September 2018 with a largest movement of 971.8 mm. ②Localized movement and tension crack throughout the entire slope at the top. The global stability of the slope is relatively questionable. ③the slope monitoring data indicate that a slope stability hazard is existed in this building slope and the in-depth stability evaluation of this building slope is suggested so that a comprehensive mitigation plan can be implemented. Continued movement monitoring of the slope is also suggested.
