Abstract:In this paper, the undrained shear strength of cohesive soil characteristics and variation of earth pressure on retaining wall of the theory are reviewed, citing previous studies, the effective consolidation stress method are outlined, proposes to use effective consolidation stress method the calculation of earth pressure on retaining wall and formulas. Then combined with the specific engineering examples ,the effective consolidation stress method is applied to earth pressure of retaining walls on both sides of the calculation. In the EXCEL table, on the same engineering examples, using effective consolidation stress method, Rankine-Bell Combined Calculation of Water and Soil Pressure method and Rankine-Bell Separate Calculation of Water and Soil Pressure method respectively calculation of retaining of earth pressure. Finally, according to the results obtained EXCEL spreadsheet, draw three ways to calculate the earth pressure on retaining wall by the attempt, including the active earth pressure and passive earth pressure by trying to, and draw the histogram of the different results were compared. The results showed: calculated by the effective stress method of soil consolidation pressures were less than the other two methods, three methods to calculate the active earth pressure difference is higher, especially the effective consolidation stress law and the Rankine-Bell algorithm is considered as the value of the land and water points , which is 2 times more than the former, while the three methods to calculate the passive earth pressure is negligible.
Key words:effective consolidation stress theory; earth retaining wall; active earth pressure; passive earth pressure; Combined Calculation of Water and Soil Pressure; Separate Calculation of Water and Soil Pressure;
