Calculation Study Of The Horizontal Layer Analysis Method On Earth Pressure Of Retaining Wall And Reinforced Earth Retaining Wall Based On The Triple-shear Unified Strength Theory

Strength theory is the most widely used in engineering technology of one of the basictheory of is all sorts of engineering structure strength calculation and design the necessarybasic theory, and theory research and engineering application and the effective use ofmaterials which great significance. This paper introduces the strength theory of thedevelopment process and the Mohr-Coulomb strength theory, double shear strength theory,three unified cut unified strength theory of the content and the basic principle, theexpression, etc, and based on three strength comparison analysis theory, eventually got threeshear strength theory is the most common form of strength theory, other strength theory isits special circumstances or linear approximation, and it includes all the contents of thestrength theory, the real realized the strength theory unity.This paper will apply Triple shear unified strength theory to horizontal earth pressurecalculation for retaining layer analysis and calculation of reinforced earth retaining wall，and derive the correlation calculation formulas, the formulas can be flexibly apply to allkinds of different characteristics of the filled soil materials of earth pressure calculation. Onthe basis of QBASIC software to use respectively three strength theory calculation retainingwall earth pressure of the calculation process programming. Then gets more accurate,scientific and comprehensive solution, which is expected to give full play to the materialstrength potential, reduce the construction cost and energy saving, and can guide theengineering application, and then bring certain economic benefits and social benefit.
