Abstract

The invention discloses an arc-shaped spaced pile retaining structure for a steep terrain in a mountainous area and an implementation method. An arc-shaped interval pile type soil retaining structure is formed by interval row piles, pressing beams, filling type waist beams and angular point resistance piles at the two ends. According to the structure, soil pressure behind the piles is converted into axial force along the arch axis, the axial force is transmitted to the resistance piles through the pressing beams and the filling type waist beams together, thrust in the arch axis direction is resisted through the resistance piles and passive soil pressure behind the piles together, a safe and stable supporting system is formed, and the problems that a conventional soil retaining structure is large in construction difficulty and high in safety risk are solved.

Description

technical field [0001] The invention relates to the field of steep terrain construction, in particular to an earth retaining structure and an implementation method of an arc spaced pile in the steep terrain of a mountainous area. Background technique [0002] With the advancement of infrastructure construction to remote mountainous areas, the number of anchorage and arch bridge foundation pit projects in mountainous areas is increasing. However, the mountainous terrain is complex and steep, and the cross-section of this type of structure is huge. Therefore, a large number of slope protection works need to be performed before the excavation of the foundation pit to ensure the stability of the slope. At present, the common supporting structures such as gravity retaining walls, anchor-cable retaining walls, reinforced retaining walls, and anti-sliding piles all have great limitations. Among them, the gravity retaining wall and the reinforced retaining wall have a large amount ...
