Abstract


Recent years, with the steady development of the national economy , more and more attention to the the mountain infrastructure construction , including the construction of high-grade highways is a top priority , the construction of a high-grade highways in the mountains is a very difficult task . Highway slope stability and protection control measures are reasonable issues that must be considered in the road design, construction and operation . Therefore, a reasonable evaluation of the stability and selection of suitable protective governance programs is essential . Slope deformation and instability may not only cause serious traffic accidents , but also causing huge loss of life and property of the people around . The prevention and treatment of slope failure is still a very difficult task , slope stability analysis and control techniques to conduct in-depth studies of important significance . In order to meet the needs of China 's rapid development of mountain infrastructure , for example, Hunan Province through flat highway tenders seventh K38 300-K38 360 High Cutting weathered slate slope , slope stability and protection design preliminary exploration. The main contents are as follows: ( 1) conduct a study on slope stability analysis method and the advantages and disadvantages of the common slope governance and applicable conditions ; (2) K38 300-K38 360 - slope stability limit equilibrium method sexual calculated using FLAC3D carried out in this the slope displacement field, stress field , and the plastic deformation zone simulation, and the safety factor obtained by the two methods , the shape of the slip plane , slip surfaces were two analytical methods , mutual authentication 's credibility ; ( 3 ) to consider the impact of rainfall , the the FLAC3D software on the slope stability analysis and safety factor ; (4) according to the results , on the slope ANCHORING design ; ( 5) slope prestressed anchor cable , using the the FLAC3D software for numerical simulation of slope prestressed anchor cable . Compare the safety factor of the slope around the prestressed anchor cable , the slope internal displacement and shear strain increment .
