Description
Technical field
The present invention relates to the retaining structure of extensive use in municipal engineering and the construction work, be specifically related to a kind of gravity pillar type retaining wall, belong to technical field of buildings.
Background technology
Gravity retaining wall is meant and relies on its deadweight to prevent the structure that upper side slope caves in.Its relies on self gravity to keep retaining wall stable under water, soil pressure effect, and available brick, stone, concrete constructions form, generally be unworthy of reinforcing bar or only in subrange, join a small amount of reinforcing bar, be a kind of retaining wall commonly used at present.According to the different incline directions of the wall back of the body and the variation of wall lineback bar, wall body form of fracture can be divided into face upward tiltedly, vertical, bow tiltedly, convex broken-line type and weight formula etc. are several.To facing upward tiltedly, vertically comparing with the three kinds of different suffered soil pressures of the wall back of the body of inclined of bowing, face upward suffered soil pressure of the sloping core back of the body and wall body sectional area for minimum, the vertical wall back of the body takes second place, and the sloping core of the bowing back of the body is bigger.
It is less that wall is carried on the back the wall back of the body soil pressure of facing upward oblique gravity barricade, so wall body cross section less expensive.But because the chest slope is slow than weight formula wall, so it is very steep to be not suitable for the ground horizontal wall inscription, be eager to receive the place on slope, the wall top should not place curb with the intersection point on chest slope, in order to avoid the wall body is invaded bedding, causes unbalance stress.Comparatively speaking, the bow basal area of the sloping core back of the body is bigger than the vertical wall back of the body.This wall type can not be brought into play the gravity barricade well and rely on self gravitation to keep out the effect of the pressure that bankets because center of gravity moves forward.The compacting that the sloping core of the bowing back of the body is easy to banket, but the also increase thereupon of suffered soil pressure causes section to increase.
The great advantage of balance weight retaining wall be can utilize on the weight platform banket heavily, force the whole center of gravity of wall body after move, make base stress be tending towards balanced, increase the stability of wall body, can suitably improve the native height of retaining like this, this kind wall type is applicable to the steep place of alpine terrain as the curb wall, has bigger receipts slope ability, enable under the identical situation of condition, up to selecting the same effect of other wall types for use, reduce wall body sectional area and floor space with shorter wall; But on the other hand, the structural form of weight formula barricade has limited its substrate again and can not do very greatly, therefore with regard to diffusion barricade base stress, balance weight retaining wall is on the contrary not as other forms of retaining wall, and its height that improves retaining soil also is more limited.Simultaneously because its wall body cross section, weight platform place is the design weak link, the computational analysis complexity, especially goes up and influenced significantly by dynamic loading bottom the wall back of the body wall wall back of the body it on, has the stress concentration phenomenon, so should not use in bearing the barricade of dynamic load.
Aspect construction technology, the wall back of the body is faced upward oblique gravity barricade to be needed to build barricade by laying bricks or stones after the first excavation slope, so that the wall back of the body is fitted closely with slight slope; Gravity barricade that the wall back of the body is bowed oblique and weight formula barricade need the essential work plane of excavation earlier usually, build barricade then by laying bricks or stones, carry out backfilling compaction again.Limited by construction technology, this class barricade can not be used for building by laying bricks or stones earlier barricade, the operating mode of excavating again.
The wall back of the body is faced upward oblique gravity barricade and is received a little less than the sloping ability, and floor space is big; The gravity barricade that the wall back of the body is bowed oblique is because out-shift of gravity center, the self-stabilization ability, and cross-sectional area is big; The computational analysis complexity of weight formula barricade, comparatively responsive to dynamic load.Simultaneously, these gravity barricades are limited by worker's method, can not be applied to build by laying bricks or stones earlier a retaining, the engineering of excavating again, and be not suitable for being applied to building dense, the restricted area of construction operation face.In addition, for adopting excavation back supporting construction scheme earlier in the traditional gravity formula barricade, there is the original soil body unloading in excavation back, the distortion problem of unstable.
In sum, the gravity barricade of various conventionally forms is restricted by various external factor, and the scope of application is separately arranged.And the gravity barricade of above various types needs the bigger scope of operation during construction, vibrate, noise is big, and is big to the surrounding enviroment influence.Therefore, for needs in building dense, the restricted area of construction operation face, the design-build floor space is little, strong, the good stability of the sloping ability of receipts, and to the little barricade of surrounding enviroment influence, the advantage of necessary comprehensive above-mentioned various forms barricade, maximize favourable factors and minimize unfavourable ones design innovation, the novel gravity barricade of active adoption.
