Research On The Application Of (Composite) Geosynthetics In The Road Drainage Facility Of Western Part Of China

On the basis of drainage design and research of drainage facilities, as well as experiences of projects application interior of country and overseas, the application research is carried out relying on the real highway project. Through the investigation of projects application conditions of the common drainage facilities and relative materials in western regions at present, the design theory and methods, as along as the category of drainage facilities in western highway drainage design are analyzed. According to the investigation, the means of applying the (compound) geosynthetics in the drainage facilities is studied. In connection with the outdoor test road, integrating theoretical analysis, the compatibility and performance in service of design method is evaluated comprehensively and systemically in road drainage facilities with geosynthetics. This paper presents the property and technical standard of geosynthetics in drainage facilities with geosynthetics.This paper relates comprehensively the road waterproof and drainage facilities, hydraulic analysis method, analysis of the existed problem. The design theory of road drainage applying geosynthetics is presented. Depending on the results of laboratory test and in-site test, the technical property, design method, quality index of geosynthetics in road drainage facilities were tested and analyzed in this paper.This paper also puts forward as well the construction method and technique of geosynthetics in road drainage facilities.
