Verification Analysis of the Relationship Between Soil Pressure and Displacement of Retaining Structure

Abstract Variation laws of earth pressure accounting for the displacement are taining wall can be well described by mathmatical fitting in study relationship between and retaining displacement. The common mathematical function expressions divided into sinusoidal model, exponential like hyperbolic semi-numerical semi-analytical model function, etc. characteristics shortcomings current expression summarized. Then combined with field test test, applicability various functions predicting structures analyzed. results show that when is small, quasi-exponential close to measured results. When structure large, better. For prediction passive area, buried depth has a great influence. And error theoretical value actual influence on result model.
