Experimental Research on Earth Pressure of Double-sided Reinforced Earth Retaining Wall

According to a highway expansion project, this paper makes field obversations on earth pressnie of double-sided reinforcement retaining walls and studies distribution of it. Test results show earth pressure on the back of double-sided reinforcement retaining walls grows with increase of filling height during construction and the distribution is nonlinear along with height of the wall, the maximum is at the base. Measured values of vertical earth pressure are lower than theoretical ones. And this structure of double-sided reinforcement retaining walls has low requirement on bearing pressure of foundations. The results can be used as a reference for further application in future.
