Horizontal embedded anchorage foundation

Abstract

The invention relates to a horizontal embedded anchorage foundation and relates to the technical field of bridge engineering. The horizontal embedded anchorage foundation comprises an anchor body, anembedded wall, a buttress, a cable-stayed beam and an anchor chamber. As the embedded wall is arranged below the bottom surface of the anchor body and is horizontally embedded in bed rock, a larger part of anti-slip bearing capacity can be provided for the anchorage foundation; and compared with a gravity type anchorage foundation, the required anchor body weight is smaller when the same; in addition, a boss is arranged at the bottom of the anchor body to meet the requirement of an anchoring system for an anchoring space, and the situation that the foundation pit excavation amount is increaseddue to overall downward moving of the anchor body base surface can be avoided; and the bottom surface of the boss is arranged on the sea level or above the underground water level line, so that underground water can be prevented from immersing into the anchor body to influence the durability of the main cable anchoring system anchored in the anchor body boss. Therefore, the anchor foundation scale can be reduced, the material consumption can be reduced, the mountain excavation amount can be reduced, and the durability of a main cable anchoring system can be ensured.

Description

technical field [0001] The application relates to the technical field of bridge engineering, in particular to a horizontal embedded anchorage foundation. Background technique [0002] Suspension system bridges, as one of the long-span bridge types, are often used in sea-crossing bridge projects. As the main force-bearing member of the suspension system bridge, the anchorage is often limited by many factors, such as the coastal ecological red line, coastal topography, coastal hydrogeology, port and wharf, etc. [0003] In related technologies, gravity anchors or tunnel anchors are usually used as anchorage foundations for the main cables of suspension bridges under coastal slope terrain and bedrock geological conditions. The gravity anchor foundation resists the horizontal pull of the main cable through the friction between the base and the foundation, and the friction is equal to the product of the self-weight of the anchor after deducting the vertical component of the main...
