Research on the Mechanical Characteristics of High-Filled Balanced Retaining Wall—Taking a Retaining Wall Project in Mianyang as an Example

As a special form of gravity retaining walls, counterweight retaining walls are mostly used to ensure the stability of fill slopes. The D24-D30 section of a retaining wall project in Mianyang is mainly used to support artificial fill slopes with a height of about 10m in the site. It is proposed to consider the use of counterweight retaining wall support for such large fill slopes. Based on this project, this paper derives the calculation formula of earth pressure, which shows that the height of the upper wall is positively correlated with the earth pressure value of the upper wall, and negatively correlated with the earth pressure value of the lower wall; the unloading capacity is getting stronger and stronger, and the position of the counterweight platform has a greater influence on the increase of the earth pressure on the upper wall.
