The Site Monitoring Of Xikengkou Slope And Treating Effect Analysis

As Chinese transport development, in the mountains and complex geological situation areas, highway construction and alterations to the existing national highway has been actively developed. In such projects there will be a large number of high slope problems. In some slope slide will occur because of a long period of rain or improper construction measures, which make the threat to the road safety and traffic comfort. Monitoring has always been an important component in the slope engineering, by which the development, the trends and the treatment effort of the landslide can be understood.Based on the slope near Xikengkou in 205 national highway,the research on stability analysis method and monitor technology to the accumulative stratum landslide is done according to the study topic of communications department in Zhejiang Province:"the research the monitoring to the landslide on the rural national highway route and the construction assessment."The main research contents are as follow:(1) The factor of safety is calculated and the stability of the slope is evaluated, with the Imbalance Thrust Force Method. The impact of the cohesion and internal friction angle to the safety factor has been analyzed.(2) According to the slope of the characteristics of slope, the slope monitoring program was designed and a set of monitor measure in line with the actual situation was implemented. (3) The wavelet de-noising was used to the monitor date. Based on the rock block and fractal theory, the potential sliding surface position is determined, the criterion of evaluation of construction measures is proposed and the assessment of the development and the trends of the landslide is made.(4) According to information obtained by monitoring the slope, construction measures and the engineering investigation of the modifications have been made. The result shows that the altered construction measures achieved good results.
