Numerical Simulation On High Steep Slope Protection Measures

With the continuous progress of technology and the development of economy, the research and development of retaining structure has been developed in our country retaining structure types include not only traditional structures such as gravity retaining wall, and many of the new combination of supporting structure has been applied and engineering practice, to prevent the accident of retaining wall the occurrence, so the supporting and retaining structure is studied, ensure the supporting and retaining structure of the security, has the vital significance.This paper introduces the calculation method of soil pressure acting on the retaining wall and anchor. Take a high and steep slope protection engineering for example, the stability of different types of retaining wall are simulated. When the cantilever retaining wall can not meet the requirements of the stability, the anchor can be used to increase the stability of structure. In this paper, though the FLAC5.0software, several kinds of retaining wall in different condition are establish simulating analyzing and comparing the horizontal displacement, vertical displacement and soil shear strain of retaining wall structure, the results showed that, for the same condition of gravity vertical wall with an incline angle from its back, the anti slip and anti overturning stability of gravity retaining wall obtained certain enhancement. Through the simulation results, for the cantilever retaining wall and combination supporting structure numerical, results show that increased anchor retaining wall after anchor and cantilever retaining wall collaborative work, anti slip and anti overturning stability are enhanced, meeting the requirement of contented and light further structure in design. The position and the number of anchor bolt will affect the stability of the retaining wall. Double row anchor retaining wall is more stable than those of single row anchor rod, and the stability of anchor is installed along the upper than that is in the lower position.
