The Slope Monitoring Project In G7611 Expressway In Yunnan Province
Project Background
The slope is located on the left side of the G7611 Douxiang Expressway, between mileage pile numbers CQZK0+140 and CQZK0+185. In September 2020, a layered landslide occurred in this section, with the main sliding direction oriented at NW318°, nearly parallel to the slope orientation. The rock types of the slope consist mainly of interbedded mudstone and silty sandstone.
Project Solution
Based on the characteristics of the landslide body and stabilization structures, a total of 7 monitoring cross-sections were designed along the main sliding direction.Surface deformation and deep deformation monitoring were conducted on the landslide body. For the stabilization measures, anchor cable force, anti-slide pile strain, and soil pressure monitoring were implemented. Additionally, vibration acceleration monitoring was performed on-site to collectively form an automated landslide monitoring system.
Project Outcomes
By utilizing automated monitoring means, conduct all-weather remote online monitoring on landslides and their triggering factors. Dynamically grasp the real-time conditions of the landslide body, further enhance the proactiveness and scientific nature in disaster prevention. Minimize casualties and property losses caused by disasters to the greatest extent possible, and enhance highway slope disaster prevention and control capabilities.
