Self-resetting slide-resistant pile structure with energy consumption function and implementation method thereof

Abstract

The invention discloses a self-resetting slide-resistant pile structure with an energy consumption function and an implementation method thereof. The self-resetting slide-resistant pile structure is composed of a reinforced concrete pile body, a reinforced concrete retaining wall, an EPS (expandable polystyrene) filling layer and spring devices. The self-resetting slide-resistant pile structure is characterized in that the section size of a cantilever segment is larger than that of an anchorage segment, and the place between one side, close to the mountain, of the cantilever segment of the slide-resistant pile and the retaining wall is filled with the EPS material and the spring devices. The implementation method includes digging a pit segment by segment till the designed elevation for the reinforced concrete pile body, timely constructing the retaining wall after each segment is dug, binding the reinforced concrete pile body with a reinforced cage, and performing concrete pouring and curing. The self-resetting slide-resistant pile structure has the advantages that hard and flexible materials are combined, and landslide thrust is borne by the reinforced concrete structures and the spring devices under the normal condition; under the seismic condition, due to the flexibility of the EPS material, energy dissipation effect is excellent, and residual displacement of the slide-resistant piles after the seismic is reduced by the aid of restoring force of the spring devices.

Description

technical field [0001] The invention is a structure invented mainly for improving the anti-seismic performance of the anti-slide pile project and reducing the residual displacement of the structure after the earthquake, and is especially applied to projects with high anti-seismic fortification intensity and areas where geological disasters occur frequently. Background technique [0002] In recent years, there have been many major earthquakes in China, such as Wenchuan in Sichuan, Yushu in Qinghai, and Zhangxian in Minxian, Gansu, which have brought huge losses to people's lives and property. Therefore, the situation of earthquake prevention and disaster reduction in my country is very severe. Anti-slide piles are a commonly used engineering method in the management of geological disasters. They are widely used in engineering fields such as railways, highways, and water conservancy. However, the seismic performance of this rigid structure and the residual displacement caused b...

Problems solved by technology

However, the anti-slide pile structure cannot effectively reduce the residual displacement of anti-slide piles and slopes after the earthquake, which may lead to excessive deformation of the structure and affect normal use, which is not consistent with the current international design concept of performance-based design match
