Load Bearing Characteristics of Prefabricated Ecological Retaining Wall

Aiming at the disadvantages of traditional column slab wall, such as poor drainage performance, poor greening ability and low degree of prefabrication, the column of column slab wall is segmented and hollowed out, and the components are connected by bolts. By improving the retaining plate, a shutter shaped retaining plate is obtained. In order to determine its applicability and safety, the full scale destructive test is carried out firstly, and then the three-dimensional numerical simulation of this kind of retaining wall is carried out by using ABAQUS finite element software. The following conclusions are obtained: when the load reaches 202.5 kN, the moment at the bottom of the column, that is, when the bending moment reaches 337.50 kN·m, it reaches the limit state of normal use; when the load reaches 335 kN, take the moment at the bottom of the column, that is, when the bending moment reaches 558.33 kN·m, it reaches the limit state. This kind of retaining wall is different when it is used for the shoulder wall and the embankment wall, which shows that when it is used for the embankment wall, it is an open bulging "U" curve, while when it is used for the shoulder wall, it is a closed bulging "U" curve. With the increase of vehicle load distance, the force reduction rate of retaining wall structure first increases and then decreases.
