    • Abstract
  • In recent years, with the increasing scale of construction in China, the safety issues of multistage high slope have become increasingly prominent, and it is necessary to monitor and warn the slope work. A comprehensive three-dimensional automatic slope monitoring system based on a high slope reinforcement work instance of Zhouqu reconstruction project after disaster is established. Through monitoring and analysis of the slope of stress and displacement, it is found that the changes of the slope in the characteristics and laws during the construction and operational phases are: as follows during the initial phrase of slope support, the stress and displacement amplitude is greater. With the mutual adjustment of internal support structure and rock slope, both changes are stable. The maximum displacement speed of this slope is 0.25 mm/d﹤0.5 mm/d, accumulated variation of the maximum displacement is less than 10 mm. The force and deformation lattice beams are also in the elastic range. Based on the monitoring results, it can be drawn that the anchor lattice beam can play an effective reinforcement effect, and during the operational phase this slope is in a stable state. The test has certain reference value for the reinforcement design and monitoring analysis of similar slopes in the future.
