Study on the Structural Design Partial Coefficients of Reinforced Earth Structures Based on the Least Square Principle
According to the determining methods of the structural design partial coefficients, under two basic combinations of loads, the optimum action and resistance partial coefficients are obtained about the inner stability of reinforced earth structures based on the least square principle. They include permanent action partial coefficient = 1.2, heap load partial coefficient =1.3, vehicle load partial coefficient =1.4, reinforced materials resistance-breakage partial coefficient =156、 resistance-pulled out partial coefficient =1.52,and the results show reasonable by engineering examples checking. The paper provides a reference to the new code based on probability critical state in reinforced earth structure design.
