Anti-frost heaving and anti-seismic composite foundation structure

Abstract

The invention discloses an anti-frost heaving and anti-seismic composite foundation structure. The anti-frost heaving and anti-seismic composite foundation structure includes a plurality of rigid captype piles, a coarse sand cushion layer, a rubber pebble stiffened cushion layer, a rubber quake isolation cushion layer and a raft plate, the multiple rigidity cap type piles are evenly arranged in foundation soil, the coarse sand cushion layer is positioned on the foundation soil, the rubber pebble stiffened cushion layer is located on the coarse layer, the rubber quake isolation cushion layer is located on the rubber pebble stiffened cushion layer, the raft plate is located on the rubber quake isolation cushion layer, a blocking plate is placed on the periphery of the coarse sand cushion layer, the rubber pebble stiffened cushion layer, and the rubber quake isolation cushion layer, a building is built on the raft plate. The foundation structure can effectively prevent the foundation frost heave and the earthquake damage deformation and fracture under earthquake in a cold area, improve the mechanics performance of the foundation structure; effectively lower or avoid the enormous economic loss caused by the earthquake and the freezing damage.

Description

technical field [0001] The invention belongs to the field of anti-freezing and anti-seismic foundation, and in particular relates to a composite foundation structure for anti-frost heaving and anti-seismic. Background technique [0002] my country's permafrost areas are widely distributed, and a large number of buildings are built on foundations with severe frost heave. Failure to adopt effective frost heave prevention and control measures causes deformation and damage, which brings huge economic losses and safety hazards. obstacle. At the same time, my country is located in the Pacific Rim and the Eurasian seismic belt, and the intensity of earthquake disasters is large and frequent. The traditional seismic design adopts the design method to improve the strength, ductility, and stiffness of the structure. The seismic energy is consumed by the structure, often resulting in concrete cracking and steel yielding. question. When a rare strong earthquake occurs, although excessiv...

[0002] my country's permafrost areas are widely distributed, and a large number of buildings are built on foundations with severe frost heave. Failure to adopt effective frost heave prevention and control measures causes deformation and damage, which brings huge economic losses and safety hazards. obstacle

At the same time, my country is located in the Pacific Rim and the Eurasian seismic belt, and the intensity of earthquake disasters is large and frequent. The traditional seismic design adopts the design method to improve the strength, ductility, and stiffness of the structure. The seismic energy is consumed by the structure, often resulting in concrete cracking and steel yielding. question

In the event of a rare strong earthquake, although excessive acceleration and interstory displacement cannot cause the building to collapse, it cannot operate normally
