| Suspended-anchor retaining wall is a light combination walls with cantilever retaining wall and anchored plate. It is the composite structure that made of reinforced concrete walls, anchor plate, rod and filler between the walls and anchor.In recently years, with the application and development of reliability analysis in structural, geotechnical and other projects, it will be more realistic describe the security of suspended-anchor retaining wall when the reliability analysis method is used to the design and calculation of suspended-anchored retaining wall.In this paper, the author made a systematic exposition with suspended-anchored retaining wall of reliability analysis method, and compared the different calculation methods. The analyses or discussions are emphasis on the following contents.(1) The random variables, such as:internal friction angle, filling density, basal friction coefficient and base bearing capacity, were discussed that involved the suspended- anchor retaining wall of reliability design.(2)The author discussed some calculation methods of the reliability index, and applied it in suspended-anchored retaining wall of reliability design.(3)According to the reliability theory of the suspended-anchor retaining wall, established the limit state equation of overturning, anti-slip, bearing capacity the stability of.(4)Based on MATLAB software, use of JC method, Monte -Carlo method, optimization methods, developed the reliable indicator calculation program of the overturning moment, anti-slip, bearing capacity of the stability.(5)Take a certain same retaining walls of Yanan-Ansai Highway as example, the author compared the safety factor method calculation with the reliability design method calculation. The results proved whether the safety factor method or the reliability design method is safe and reliable. |
