A kind of double-limb energy-consuming anti-sliding pile and its construction method

Abstract

The invention relates to an energy-dissipating anti-sliding pile with two limbs and a construction method thereof. The anti-sliding pile includes a main limb pile body, an auxiliary limb pile body, a sliding pair and an energy-dissipating connecting rod system. The anchorage section of the main pile body is the anchorage section of the anti-sliding pile, and the small section of the upper part of the main pile body forms the load-bearing section of the main pile body; the auxiliary pile body is located on the side close to the mountain, and the bottom of the auxiliary pile body passes through the It is connected with the variable cross-section in the middle of the main pile, so that the auxiliary pile can have a certain horizontal displacement relative to the main pile; the auxiliary pile, the energy-dissipating connecting rod system and the loaded section of the main pile constitute the anti- The loaded section of the slide pile. When an earthquake occurs, a certain relative displacement is allowed between the auxiliary leg pile and the main leg pile, and the energy-dissipating connecting rod can effectively dissipate the input energy of the earthquake and ensure the function of the main leg pile within the allowable displacement range, so as to achieve The purpose of anti-seismic energy consumption and protection of anti-slide piles is to improve the seismic stability of the slope and ensure the normal working performance of anti-slide piles after earthquakes.

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...

Problems solved by technology

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 body topples, or a large permanent displacement occurs, which affects the normal use function after the earthquake
