Horizontal embedded anchorage foundation
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.
本申请涉及一种水平嵌入式锚碇基础，涉及桥梁工程技术领域，包括锚体、嵌入墙、支墩、斜拉梁和锚室，由于嵌入墙设于锚体底面以下且水平嵌入在基岩之中，故可以为锚碇基础提供较大一部分抗滑承载力，与重力式锚碇基础相比，在满足相同抗滑承载力时，所需锚体重量更小；另外，锚体底部设有凸台以满足锚固系统对锚固空间的要求，可避免将锚体基底面整体下移而导致基坑开挖量增加；凸台底面设于海平面或地下水位线以上，可避免地下水浸入锚体之中影响锚固于锚体凸台中的主缆锚固系统的耐久性。因此，本申请不仅可以减小锚碇基础规模、节省材料用量、降低山体开挖量，还可以确保主缆锚固系统的耐久性。
