A general gravity type retaining wall refers to a retaining wall that resists the lateral pressure of a soil body by the self weight of a wall body. The gravity type retaining wall can use block stones, sheet stones and concrete precast blocks as masonry, or adopt sheet stone concrete and concrete to perform integral casting. The semi-gravity retaining wall can be cast by concrete or less-reinforced concrete. Gravity retaining walls can be constructed of masonry or concrete and are generally made in a simple trapezoidal shape. Its advantages are use of local raw materials, convenient construction and high economic effect. Therefore, the gravity retaining wall is widely applied to the projects of railways, highways, water conservancy projects, estuaries, mines and the like in China.
