Geosynthitic-reinforced soil gravity retaining wall (GRSGRW) has been applied more and more to the practical engineering projects in recent years. Due to be short of systematically research on the working properties of the new retaining wall system
the design theory and method for GRSGRW in the relative codes in China are not yet regulated; so some design methods based on experiences
which are short of the theoretical foundation
have to be applied to the design of GRSGRW. In this paper
taking a construction sequence (filling geosynthitic-reinforced soil after finishing the pouring of gravity retaining wall) into account
the working properties of GRSGRW are simulated by means of FLAC2D. The effects of geogrids on the horizontal displacement of gravity retaining wall
and the horizontal displacement and the horizontal stress of filling,as well as the changing of geogrids tensile stress and tensile strain with the filling stages are analyzed. Based on the analytical results
a method for calculating soil pressure acting on the back of gravity retaining wall is suggested.
