Dynamic Monitoring and Strengthening Construction of High Slope Near Deep Foundation Pit
Taking a large foundation pit project in Longyan City,Fujian Province as an example,the deformation characteristics of the slope during foundation pit excavation are deeply analyzed,and the slope reinforcement measures are proposed based on the deformation characteris-tics.According to the monitoring data,blasting excavation and rainfall seriously affect slope deformation,resulting in slope instability;The in-crease rate of instability deformation after reinforcement is much lower than that before reinforcement,and the decrease of maximum displace-ment at the two monitoring points after reinforcement is 69.7%and 47.9%,respectively.It shows that the slope reinforcement measures are safe and reliable,and the reinforcement effect is good.
