However, with the continuous increase of the span, the load borne by the anchorage foundation is also increasing. Usually, the "extensive" design method develops the anchorage foundation in a deeper and larger direction, which not only leads to construction costs and The increase of the cycle will also bring unnecessary difficulty to the construction and cause great damage to the environment.

Embodiment Construction
[0074] Such as Figure 1-3 As shown, a shallow-buried anchor foundation base anti-slip device includes three anti-slide root keys embedded in the anchor foundation base plate 10, and these three anti-slide root keys are long strips with a rectangular cross-section. For the reinforced concrete member, the length directions of the three anti-sliding root keys all extend horizontally perpendicular to the tension direction of the cables 12 .
[0075] Specifically, the three anti-skid keys are respectively the central anti-skid key 2 located in the middle of the anchorage base plate 10, and the front toe anti-skid keys arranged symmetrically and parallelly on both sides of the central anti-skid key 2. 1 and rear toe anti-skid root key 3. The three anti-skid keys equally divide the diameter of the anchorage base plate 10 in the direction of the horizontal force component of the cable 12 tension, that is to say, the front toe anti-skid key 1, the central anti-skid key 2 and the rear...

The invention discloses an anti-skid device, a size determination method and a construction method for a shallow-buried anchor foundation base. The sliding root key can significantly improve the anti-slip ability of the bottom of the anchorage foundation and the stability of the anchorage foundation. The method for determining the size of the anti-sliding device can effectively avoid the shielding of the passive earth pressure of the anti-sliding root key, and avoid the influence of the passive earth pressure of the anti-sliding root key on the stressed members of the existing structure. The principle of the method is clear and the calculation process Simple, easy for technicians to apply. The provided construction method has strong practicability, convenient construction and strong economy. The invention provides an effective guarantee measure for the safe application of the shallow-buried anchorage foundation, and plays an important role in the further popularization and application of the shallow-buried anchorage foundation in bridge engineering in my country.
Description
technical field [0001] The invention relates to an anchorage foundation of a suspension bridge, in particular to an anti-skid device for a shallow-buried anchorage foundation base, a size determination method and a construction method for the anti-skid device. Background technique [0002] Gravity anchorage foundation is one of the main anchorage foundation forms of suspension bridges, and the displacement of the anchorage under the action of huge main cable tension will have a huge impact on the entire stress situation of the bridge. The anchorage foundation mainly relies on its own weight to resist the vertical component load of the main cable tension, and relies on the frictional resistance of the base and foundation to resist the horizontal component load of the main cable tension. In order to strictly control the displacement of the gravity-type anchorage foundation, a deep-buried anchorage foundation is usually selected, so that the bottom of the anchorage foundation i...
