Abstract

The invention relates to a double limb energy-consuming anti-slide pile and a construction method thereof. The anti-slide pile comprises a main limb pile body, an auxiliary limb pile body, a sliding pair and a energy consumption linkage system, a main limb pile body anchorage section of a large cross section of the lower portion of the main limb pile body forms the anchorage section of the anti-slide pile, and a small section of the upper portion of the main limb body forms a main limb pile body bearing section; the auxiliary limb pile body is located near the side of a mountain, and the bottom of the auxiliary limb pile body is connected with an variable section of the middle of the main limb pile body through the sliding pair so that the auxiliary limb pile body can be horizontally displaced relative to the main limb pile body; the auxiliary limb pile body, the energy-consuming linkage system and the main limb pile body bearing section constitute the bearing section of the anti-slidepile. When an earthquake occurs, a certain relative displacement is allowed between the auxiliary limb pile body and the main limb pile body, the energy-consuming linkage system can effectively dissipate the seismic input energy and ensure the function of the main limb pile body within the allowable displacement range, and the purpose of seismic energy consumption and protection of the anti-slidepile is achieved to improve the seismic stability of a slope and ensure the normal working performance of the anti-slide pile after the earthquake.

Description

technical field [0001] The invention belongs to the anti-seismic field of slope engineering, and in particular relates to a double-limb energy-dissipating anti-slide pile structure and a construction method thereof, which are mainly suitable for slope engineering and landslide control engineering with high seismic fortification intensity. Background technique [0002] Anti-slide pile is a common slope engineering support measure, which is widely used in railway, highway, water conservancy and other engineering fields. my country is an earthquake-prone country, and the support measures for side landslides not only meet the support requirements of static conditions, but also need to have good seismic performance. Most of the traditional anti-slide piles are whole large cross-section reinforced concrete piles with simple structure, single function and high rigidity. This kind of rigid anti-slide pile is prone to structural cracking under the action of an earthquake, the pile b...
