Mountain Highway Slope Monitoring Construction, And Information Design

The paper taking Tong-Huang expressway AK3+690～AK3+888 left side deep cut rock high slope as an example,based on predecessor research data and geology survey,study the stability of high slope and handling measure by the use of engineering of geology, geotechnical engineering,rock mechanics and numerical simulation.Meanwhile, the paper provides the suggestions of information design and construction on the basis of monitoring data combined with the analysis of geology engineering.Also,partly theory and techniques of information design and construction is concluded.Detailed contents of this paper is following:1 .Based on the inside survey of high slope and slope engineering geology conditions, the mechanism of deformation, the failure mode of the slope and the primary factors influencing the stability of slope is verified. Qualitative and quantitative slope stbility evaluation is carried out by the use of test parameter, mathematical analysis and different slope stability methods.2..Based on the foundation of analysis of the data from monitoring the slope movement and the cable stress,the stability of the high slope was found out.At the same time,the appraisal of the result of protection to high slope has been concluded.3.The reinforcement of the high slope is analysed by the numerical simulation and the mutual function of the geologic body and engineering structure is also given.The anchor structure action mechanism is clearly explained in order to evaluating the long-term stability of high reinforced slope. Through the stability evaluation,the stability of the slope have been cleared..4. According to analysis of the depth displacement monitor data and the anchor cable stress monitor data, the information design and construction is carried out combined with in-site survey,the original design and the construction plan.
