The Composite Slope Supporting Forms In The Research And Evaluation Of Application Effect Of Ganlong Railway

In the back ground of the requirement that the Ministry of Railways construct "high qu ality, safe, green, harmony" railways,Conducted using the form of combined supporting mode with cable anchor gag constructions.Anchor wall,anchorpiles,after the end of the construction,then use plants protection slopeit will reduce the using of steel,cement t o save masonry. In this kind of supporting structure,anchor cable and lattice anchor r od retaining wall has played a major role, Therefore,it is important significant to rese arch supporting effect of anchor cable and lattice anchor rod retaining wall composit e slope support form to guide the difficult and complex mountain high slope support design and constructionThe paper is combined with the reconstruction of Ganlong rail Shanghangbei Sta tion high slope excavation and support processes,through the method of field monitori ng,numerical simulation and comprehensive evaluation,researching and evaluating the a pplication effect of the gag type anchor retaining wall anchor form.In accordance wit h the access to information-Field monitoring-Data Analysis-Modeling-Simulation-Supp orting Evalution. The main contents of this paper include:1.We have selected four representative sections of slope in Shanghangbei Station ,established a set of monitoring systems including Deep displacement, the reinforcem ent stress, the anchor stress and the soil pressure under the framework.2.In this paper,we have analyzed the field monitoring data of the displacement, t he rebar strain meter, the cable strain gauge and the soil pressure gauge, we use the relevant professional knowledge to analysis the solpe deformation,stress development. Then combination with field monitoring data, determine the stability of the slope.3.In view of the slope,we use FLAC3D numerical simulation analysis,which based on the coulomb-Moore criterion analysis the four monitoring cross section slope in two conditions, including excavation support and support state, it is concluded that the displacement of the slope deformation, The axial force of retaining structure and stability coefficient of variation. Combining with field monitoring data, the supporting effect of the slope was studied.4.1n this paper,on the basis of predecessors’ research supporting effect evaluation, for the first time, we evaluate the effect of the prestressed anchor rope support technology condition,and from the slope supporting effect form suitability,local working state,technical conditions and the overall impact of the security situation to evaluate the effect of the application in the form of the supporting system using the composite slope support.
