Study on influence factors of passive earth pressures of retaining walls

According to the wall deformation monitoring records during the engineering construction of the retaining wall ditch of the Zhenhai Villa in Qingdao,we can find that the soil filling of the retaining wall has caused the passive earth pressure that has already protected the wall.This paper mainly analyzes the relationship between the passive earth pressure and the effective width after the retaining wall being dealt with effectively,which is of great significance for the design,safety evaluation and reinforcement of the retaining wall.
