However, the wall body has a large cross section and a large number of masonry, so that the requirement on the bearing capacity of the foundation is high, the construction on a weak foundation is not suitable, and the height of the wall body is generally below 8 m. The balance weight type retaining wall utilizes the filled soil on the balance weight platform and the gravity center of the whole wall to move backwards so as to increase the stability of the wall body and reduce the section size. The wall has steep chest and inclined lower wall back, so that the wall height can be reduced and foundation excavation can be reduced. The method is suitable for the shoulder wall in mountainous areas and steep ground transverse slopes, and can also be used for cutting walls or embankment walls. The cantilever type retaining wall is made of reinforced concrete materials and consists of three parts, namely a vertical wall, a wall toe plate and a wall heel plate; the section size is smaller. The bending moment of the lower part of the force arm is large when the wall is high, and the consumption of steel bars is large. Is suitable for areas lacking stones and areas with retaining wall height not more than 6 m. These retaining walls are rigid retaining walls, and although they can prevent the movement of the soil behind the wall well, the retaining wall structure itself is heavy, the masonry amount is large, the requirement for the bearing capacity of the foundation is high, and the retaining wall cannot be planted and green, and is not suitable for areas lacking stone.
