Mountainous Shoreline Road Subgrade Deformation Stability Monitoring And Disease Control Techniques

With the continuous development of China’s transportation infrastructure, traffic conditions in mountainous areas has been greatly improved. However, due to the terrain and the requirements of developing roads’ line, most loads spread close the river or brook. Longitudinal gradient of the mountainous rivers or streams is always large, and it is likely affected by seasonal runoff, water levels mutations in reservoirs, rivers and others often caused by rainfall mutations in the rainy season. This process has a significant impact on the stability of the roadbed. On the one hand, the water level rising will make the Shear resistance parameters decrease; on the other hand, Embankment slope stability problems caused by the sudden changes of hydraulic condition particularly prominent. Therefore, conducting stabilization of mountainous shoreline road subgrade deformation monitoring and Disease Control technology research is very important.This article summarize existing research results, Through the measures of theoretical analysis, practical engineering application and so on, it makes a comprehensive and systematic study on stabilization of mountainous shoreline road subgrade deformation monitoring and Disease Control technology, the main research results are as follows:Firstly, it analyzes the characteristics of mountainous shoreline road embankment and the flow in mountains and their impact on shoreline road, the working conditions of mountainous shoreline road subgrade and the stability and security’s status quo of Reservoir Reservoir embankment were obtained preliminarily,and proposed classification method of the mountainous shoreline road subgrade,Secondly, in order to understand highway slope of the reservoir area, operational status retaining structures, analysis of its key disease types, the project team in Chongqing, Sichuan, Yunnan, Shaanxi and other provinces shoreline road conducted an investigation,.Thirdly, based on working principle of monitoring instruments, it proposed principle of selection and arrangement of bank embankment observation instruments and sensors, including the site monitoring, data acquisition, solar power supply, data wireless transmission, the monitoring center module, data management and analysis of reservoir bank subgrade deformation stability monitoring system have been built.Lastly, by Yunnan Wenshan - Long secondary road this project are examples of commonly used analysis method of bank roadbed Disease Treatment, including the excavation of Replacement, compaction replacement, pressure grouting. In addition, the description of the deformation stable roadbed stability remote wireless monitoring of the implementation of the method and the results of the analysis.
