Abstract

The invention relates to a method utilizing a horizontal interlayer between foundations to avoid destructive effect on building upper structure from earthquake horizontal waves. The method includes designing one or more than one rafts between foundations, designing one or more horizontal separating layer (sand-gravel cushion) smooth surface (slabs with different upper and lower materials and minimum friction index) between the rafts, thereby eliminating and avoiding transmission of earthquake horizontal waves from up to down and from foundation to foundation after the upper and lower structure of the foundations are separated, and then maintaining safety and stability of upper structure of buildings. Passive resistance from the upper main structure is changed to positively eliminate source from lower foundations. Energy from earthquake horizontal waves can be freely released from horizontal layers between foundations, and safety and stability of the upper building main structure can be maintained when the foundations release earthquake energy. The method is a major breakthrough for high layer buildings to resist earthquake disaster, is low in cost, feasible and convenient, and good in earthquake effect.

Description

1. Background technology [0001] After the 1.1 and 512 earthquakes [0002] There is such a building community in Baoji, two buildings with the same six floors, one is a lime-soil pile foundation, the pile tip soil is loess-like silty clay, and the buried depth is about 8.0m; the other is a concrete pouring pile foundation, the pile tip soil It is gravel soil with a buried depth of about 16.0m. After the Sichuan Wenchuan Earthquake occurred on May 12, 2008, the superstructure of the building in the form of lime-soil pile foundations at the same site showed no obvious signs of damage, while the concrete pile foundation in the form of cast-in-place piles Obvious horizontal shear cracks can be seen on the upper part of the surrounding foundation beams of the building. [0003] 1.2. Principle [0004] 1.2.1. The damage energy and horizontal shear force of earthquakes on buildings mainly come from the seismic horizontal waves [0005] Earthquake phenomenon is due to the movement ...
