Abstract:As one of the most effective earth-retaining wall technologies MSE-Wall has been used widely all over the.world for its advantages of low cost and easy construction.Recently the geosynthetics used in MSE-Wall is gradually changing from reinforced geobelt to geogrid but there are few software designed for geogrid.This paper firstly introduced and pared the mechanical principle designing and constructing methods of reinforced geobelt and geogrid.After that the function and characteristics of self- developed software MSE calculator V1.1)programmed with Delphi is introduced.Finally the calculation procedures with reinforced geobelt and geogrid are illustrated with two engineering examples and the results are pared to other calculation methods to validate the accuracy of the software.
