Research And Analysis Of The Health Monitoring For High Slope In Zhouqu

China is a country with complex and varied topography and geological conditions, and the mountain area is larger. It is one of countries which have the most serious landslide hazard in the world. The economic loss caused by landslides every year is enormous. With the rapid development of Chinese economy scale, all kinds of civil engineering have been an unprecedented development. It produced some temporary or permanent slope engineering, and the artificial slope often occurred instability phenomenon, which often bring serious harm to people’s normal production and life. According to many experts, how to effectively prevent and control slope instability and landslide hazard has been became a significant research subject. Health monitoring has obtained the rapid development in recent years, which is regarded as an important tool to analyze the slope stability and slope engineering.The target of this paper is to research the stability of the slope after reinforcement treatment through a large-scale health monitoring trial, which based on the treatment project of Chunchang South Road east high slope in the Zhouqu reconstruction project. The trial can provide the judgment of safety and reliability for slope reinforcement engineering. The main research content is as follows:According to the principles of slope monitoring, a more comprehensive testing scheme of health monitoring for slope was designed under the condition of the project. According to the testing scheme, some kinds of sensors was set up in the construction process of slope reinforcement engineering,, and a set of remote automatic health monitoring system for slope was established successfully. By using the advanced GPS technology, two GPS displacement monitoring stations were established on the slope top in test section, and the GPS displacement monitoring system was constituted of them and the other station.By using many sensors, the displacement of slope, the displacement and internal force of, internal horizontal displacement of slope could be the real-time monitoring. And the real information of slope deformation after reinforcement and the development of the internal force and displacement for structure were obtained by the health monitoring system. According to the monitoring data, the change of the slope displacement and retaining structural internal force and displacement is small. It show that the retaining form of anchor lattice beam has a good reinforcement effect, and the stability condition of the slope is good in operation stages.
