Deformation Mechanism And Construction Information Management Of Highway Cutting Slope In Strongly Weathered-areas

A lot of problems of cutting slopes stabilization caused by special terrain and complex geology influence on the period of construction, investment and safety, which means slope stabilization of highway slope is one of the main problems of this construction. So, study on activation of landslide of this expressway to find best design and constructional management of highway is practically and theoretically useful to this project and promote the highway industry and economic.This article is finished on basis of the content and supporting project of risk assessment and countermeasures for Geological hazards in the construction of highway.First of all, the natural and geological environment was analyzed to deduce characteristics of slope and factors of slope failure, esp. the constructional factors. Then, the structure of slope was researched to get a general model of slope failure and summarize the causes to control failure processes.Secondly, characteristics and problems of exploration, design and construction being considered, the collection and analysis of information of geological and deformation in the construction of slope were proposed to prove the rationality and benefit of these stabilization and control measures for slope. The principles, manners, methods, and analysis for result, etc. were specified.Thirdly, the principles and processes of informational management for slope construction were studied by information theory. The manners and technical routes for reducing deformation were made on the basis of its nature; moreover countermeasures were prepared by the information collected in construction.At last, the application of informational management for highway construction of certain slopes practically expresses this means is beneficial and useful and has a bright prospect.
