Description
Technical field
The present invention relates to building engineering field, more particularly to a kind of building subtracts shock insulation ground.
Background technology
As Recent Seismicity is strengthened, earthquake disaster Burst frequency all over the world is also higher and higher.In order to reduce
The Loss of Life and property that earthquake natural calamity is brought to the mankind adds flexible media to form shock insulation in building basic part
Layer, is one of common method..
Soil engineering bag because of the significant advantages such as good engineering mechanical properties and environmentally protective, economy, construction be simple,
It is widely used in the basement process of all kinds of architectural engineerings.But when soil engineering bag is subtracted shock insulation ground as building, also there are more
Deficiency is mainly reflected in vertical bearing capacity and subtracts two aspects of isolation property.
Specifically, on isolation property is subtracted, filled mostly with clay or sand in previous soil engineering bag, and shape is mostly
Flat, this not only causes horizontal direction elastic restoring force weaker so that and building lot can not automatically reset after earthquake, and compared with
Small depth-width ratio makes that its own shearing rigidity is larger, shear deformation ability is weaker, therefore isolation property is poor.In addition, practical work
Cheng Zhong, in order to reduce compressed stress suffered by soil engineering bag with ensure ground safety, need to by a large amount of soil engineering bags at sustained height simultaneously
Discharge is put, and to share the total weight of upper building, this causes the whole shearing rigidity of ground bigger than normal, is difficult to superstructure reality
Existing horizontal direction shock insulation function, shear deformation ability also do not protrude.At the same time, since soil engineering bag generally uses flexible package material
Material so that be difficult to effectively transmit horizontal force between upper and lower adjacent layer soil engineering bag, the horizontal direction high damping shock absorption for causing soil engineering bag is excellent
Gesture can not also be not fully exerted.
In terms of vertical bearing capacity, because the flexible contact interface between the adjacent soil engineering bag of upper and lower layer will appear stress concentration
Phenomenon, the entire compression bearing capacity for making ground are relatively low.In fact, at present soil engineering bag gene Carrying Capacity be only applied to it is all kinds of
Light construction occasion.
Invention content
