(one) foundation and foundation
1, foundation: structural place susceptive all sorts of action pass the structural component on foundation to call a base. The foundation is the main component of housing, it bears the full load that building upside structure transmits, pass weight of these oneself of load along with ground together.
2, foundation: The earthy system that goes up for bearing foundation or cliff body call foundation. Foundation does not belong to the component of the building, but it is right those who assure a building is solid and fast have very main effect.
3, the relation of foundation and foundation:
Fundamental type and tectonic not complete decision at building upside structure, the property of it and foundation earth is having affinity. The building that has same upside structure is built go up in different foundation, the form of its foundation and tectonic likelihood are completely different. Accordingly, between foundation and foundation, having mutual effect, the affinity that restricts each other.
(2) the deepness of the foundation that bury buy and influencing factor
1, the deepness of the foundation that bury buy: Call the depth of the foundation that bury buy to the perpendicular height of fundamental bottom from level of ground of the design outdoor commonly, abbreviation is buried deep.

2, influence foundation buries deep element
(1) the utility of the building and the influence with tectonic foundation
(2) the effect impact in the load size on foundation and property
(3) the influence of project geology and hydrogeology condition
(4) foundation earth aspic bilges and the influence of defect of be in harmony
(5) foundation of photograph adjacent building buries profound influence

3) fundamental classification and construction
1, the configuration classification that presses a foundation: 1) form foundation 2) independent base 3) column lays a form foundation 4) balsa form foundation 5) box form foundation 6) picket foundation.
Form and independent base
Column lays a form foundation
Foundation of cut down form
Box form foundation
2, use material and classification of characteristic getting power by place
(１ ) expand without muscle foundation
Definition: Without muscle patulous foundation department shows by concrete of concrete or brick, rubble, rubble, ash earth is mixed 3 add up to earth to wait for material, and the wall that does not need to configure reinforcing steel bar lays a form foundation or the foundation becomes independent below column.
Characteristic: The material of this kind of foundation is fought it is better to control function, but tension, shear strength is not high, want to make sure the foundation is not destroyed by pulling force or strong shearing force, must command fundamental aspect ratio. Without muscle patulous foundation applies to multilayer and civil building and light-duty workshop.
(2) patulous foundation
Definition: the load that upside structure transmits, through expanding to side certain underside is accumulated, make action is in the press stress to be equal to or is less than foundation to go up permission of base bears the weight of force, and the intensity requirement that the stress of fundamental interior should satisfy material itself at the same time, this kind removes pressure to diffuse the foundation of action calls patulous base.
It includes the ferroconcrete below foundation of independence of the ferroconcrete below column and wall form foundation.
Characteristic: Because expand fundamental bottom matchs with reinforcing steel bar, use reinforcing steel bar to bear tensile, make fundamental bottom can bear bigger curved moment. At this moment, of fundamental width increase the limitation that does not get rigid part, can do very widely, very thin. Still but as far as possible shallow bury.
Expand without muscle of the foundation suffer the force, characteristic that send force to pursue as follows.
Expand without muscle of the foundation suffer the force, characteristic that send force
Expand without muscle fundamental construction signal pursues as follows.
Without muscle patulous foundation constructs signal
Without muscle patulous foundation constructs signal
Expand fundamental construction signal pursues as follows.
