Field test analysis of block geogrid-reinforced earth retaining wall

Through burial the level of earth pressure cell,flexible displacement meter,system monitoring the level of earth pressure and grid horizontal deformation of block geogrid-reinforced earth retaining wall,the earth pressure of reinforced earth retaining wall is calculated by reinforce combination method,comparative analysis the data of field measurement and variable coefficient method,obtained the conclusion that the earth pressure distribution of reinforced earth retaining wall on work condition is more reasonable than other method;comparative analysis the geogrid strain of the construction phase and after completion,draw the conclusion that geogrid strain occurred mainly in construction stage,strain is small in after completion.Based on test results,put forward recommendations how to control the construction.
