Geotextile bag shock absorption and vibration isolation building foundation, and construction method and application thereof

Abstract

The invention provides a geotextile bag shock absorption and isolation building foundation and a construction method thereof. The foundation consists of a geotextile bag, geotextile bag pier foundation, a geotextile bag strip foundation, a geotextile bag raft foundation and a terrace, wherein geotextile bags are horizontally and longitudinally staggered and stacked layer by layer under the terrace in the sequence of the pier foundation under the column, the strip foundation under the wall and the raft foundation under the house of the building foundation; and clearances among the geotextile bags are filled up and tamped; and reinforced concrete or other material protective layer and the like is spread on the terrace. When an earthquake happens, earthquake waves are reflected and refractedbetween the insides of the geotextile bags and the geotextile bags; and the flexible deformation of the geotextile bags and the friction movement among soil particles inside the geotextile bags as well as the friction diastrophism among the geotextile bags consume the energy of the earthquake waves, and the earthquake waves are isolated due to the discontinuity among the geotextile bags. The method has the advantages of good shock absorption and vibration isolation effects, simple construction, economy, and remarkable economic and social benefits.

Description

technical field [0001] The invention relates to a shock-absorbing and seismic-isolating building foundation and its construction method and application, in particular to a geotechnical bag shock-absorbing and seismic-isolating building foundation and its construction method and application. Background technique [0002] Seismic isolation and energy dissipation of existing buildings are basically based on setting a seismic isolation layer between the upper structure of the building and the foundation to prolong the natural vibration period of the entire structural system, increase the damping, and reduce the seismic energy input to the superstructure. Meet the expected shock resistance requirements. At present, rubber isolation bearings and damping devices are widely used at home and abroad. However, the above-mentioned seismic isolation and energy dissipation and shock absorption devices have insufficient vertical shock absorption effect and high price, so it is difficult t...

AI Technical Summary

Problems solved by technology

However, the vertical shock absorption effect of the above-mentioned shock isolation and energy dissipation devices is not good enough, and the price is too high, so it is difficult to popularize and apply them in ordinary buildings, especially in the foundations of middle and low-rise buildings in cities and towns.
