The retaining wall 1 is formed between ground 6 and the terrace 5, the retaining wall 1 is perpendicular to the indoor terrace 5 and outdoor
Foundation ground 6, and the upper surface of the retaining wall 1 is concordant with the terrace 5, the basis is goed deep into the bottom of the retaining wall 1
Inside ground 6, there is some horizontal reinforcements and some vertical reinforcements in the retaining wall 1, the underface of the retaining wall 1 is fixed
Have a grade beam 3, the lower section of the grade beam 3 is provided with the ground cushion 4, the grade beam 3 and the ground cushion 4 all with the retaining wall 1
It is isometric；
The basic stub 2 sets one, the basic stub 2 along the length direction of the retaining wall 1 every 10-15m
Parallel to the short transverse of the retaining wall 1, the basic stub 2 is contour with the retaining wall 1；
The height h1 of the retaining wall is 2.1-3m and width is 250-400mm, and described ground depth of beam h2 is the gear
1.5-2 times of the width d1 of cob wall, the width d2 of the grade beam is 2-2.5 times of the width d1 of the retaining wall.
The height h1 of the retaining wall is 2.1-2.4m and width is 250-300mm, and described ground depth of beam h2 is described
1.5-1.8 times of the width d1 of retaining wall, the width d2 of the grade beam is 2-2.2 times of the width d1 of the retaining wall.
The difference in height h having between the indoor terrace of the logistics warehouse and its outdoor foundation ground is 1.3m, institute
The height of retaining wall 1 is stated for 2.1m and width is 300mm, the height of the grade beam 3 is 500mm, and the width of the grade beam 3 is
700mm。
In the present embodiment, it is preferred that the basic stub 2 sets one along the length direction of the retaining wall every 12m.
Width of the width of the grade beam 3 less than the ground cushion 4.
The basic stub 2 be concrete foundation stub, and the basic stub 2 cross sectional dimensions for 600mm ×
600mm。
The following is comparative example and the concrete condition of embodiment, wherein retaining wall Russia is highly 2.1m, and width is 0.3m, edge
Retaining wall longitudinal direction sets a concrete foundation stub of 600mmx600mm every 12m.Comparative example is not designed in retaining wall bottom
Grade beam, embodiment is the grade beam of 500mmx700mm in one section of sectional dimension of retaining wall bottom design, is fixed as retaining wall bottom
Bearing.Two kinds of main distinctions of design can intuitively draw from Fig. 1 and Fig. 2.Retaining wall is from constructing to normally using
Process mainly experiences two kinds of stresses, and during comparative example stress is work progress, backfill is completed but room before and after retaining wall
Interior terrace is not yet completed, and this stage terrace cannot function as retaining wall top surface lateral support；Second stress is normally to use
When, retaining wall will bear soil pressure before and after wall, while bearing by terrace ground preloading in warehouse that (comparative example and embodiment are
30kN/ ㎡) the lateral earth pressure at rest that causes, can be supported as retaining wall upper lateral in this stage terrace, such as Fig. 5 .1-
Shown in 5.4.
According to two kinds of designs of comparative example and embodiment, using finite element analysis software MIDAS/GEN to retaining wall not
Internal force analysis are carried out with the stress stage.
Calculation assumption：
Comparative example when floor construction is not yet completed, using the concrete foundation stub of left and right sides 12m spacing as elasticity
Support, this stage is solely subjected to the earth pressure at rest before and after retaining wall；When serviceability limit stage is entered after the completion of floor construction, side
Boundary's condition is changed into both sides resilient support, and top freely-supported in addition to construction stage load, increased the side passed over by ground preloading
To earth pressure at rest.Embodiment assumes that grade beam is fixed in bottom when floor construction is not yet completed, and left and right flexibly supports in base admittedly
Plinth stub, upper end freedom, this same comparative example of stage stress；When floor construction completes to enter serviceability limit stage, upper bound
Condition is from being freely changed into freely-supported, and its coboundary is constant, this same comparative example of stage stress.Due to logistic storage terrace ground with
On, it is assumed that do not consider Effect of Underground Water Level, banketed before and after retaining wall from 18kN/m3 is refetched, coefficient of static earth pressure takes 0.5.
Following table is the Finite element analysis results of comparative example and embodiment and the retaining wall of embodiment is reduced into two-dimentional bar
Be model result of calculation arrange in the following table：
Retaining wall internal force (kNm)
Can significantly find out in table two kinds of boundary schemes of comparative example and embodiment retaining wall moment of flexure exist it is dramatically different.
It is worth noting that in addition to both are in moment of flexure numerically difference, both bending directions are also differed.The main edge of comparative example
Side stress long, mid span moment is big, and embodiment is mainly along short side stress, moment of flexure is maximum along the substantially uniform distribution in longitudinal direction
Moment of flexure is in support boundary.
Can significantly be found out according to result of finite element, one grade beam is set in retaining wall bottom, change power transmission
Path, can significantly reduce retaining wall moment of flexure.Comparative example due to mainly by both sides concrete foundation stub as support, earth-retaining
Wall with horizontal reinforcement be main principal rod, i.e., based on the bending of side long, embodiment due to the constraint for having bottom grade beam, retaining wall with
Vertical reinforcement is main principal rod, i.e. retaining wall based on short side bending.According to result of finite element, the retaining wall of embodiment
Construction stage and serviceability limit stage result of calculation respectively be reduced to bottom fix and bottom fixation upper end freely keep off
Cob wall result of calculation is basically identical, and Path of Force Transfer clearly, facilitates project planner to simplify and calculates.It is worth noting that this implementation
The retaining wall of example, without significant changes, can expire in two stage internal force according to the retaining wall of serviceability limit stage result of calculation arrangement of reinforcement
Sufficient construction stage force request.
The retaining wall main distinction of two kinds of forms is mainly whether bottom sets grade beam, although seems bottom and sets a grade beam
" waste " part concrete and reinforcing bar, but shown according to Finite element analysis results above, bottom grade beam is by retaining wall by growing
Side force way is changed into short side stress, and Path of Force Transfer is most short.Can be substantially reduced in retaining walls compared with the grade beam is not provided with
Retaining wall stress clearly, can be simplified to traditional two-dimentional member system model and calculate after power, and setting grade beam, facilitate designer
It is quick to calculate retaining wall arrangement of reinforcement.Because there is provided grade beam changes the stress of retaining wall, both sides basis stub is not re-used as
Main stress side, stub arrangement of reinforcement can also be reduced.
Embodiments of the invention are the foregoing is only, embodiments of the invention, and unprovoked is not thereby the foregoing is only
This limitation the scope of the claims of the invention, the equivalent structure that every utilization description of the invention and accompanying drawing content are made, or directly or
Other related technical fields are used in indirectly, are included within the scope of the present invention.
