Abstract
The invention discloses a method for improving stress performance of a retaining wall and a retaining wall structure. The retaining wall structure comprises the retaining wall, and a platform plate is horizontally arranged on the wall back face of the retaining wall; and the length of the platform plate extends to a sliding face of a sliding soil wedge of a wall back. Due to the adoption of the technical scheme, compared with the prior art, the retaining wall structure is convenient to implement. The platform plate is manufactured on the wall back face of a conventional retaining wall, and a pressure reduction structure can be formed; pressure of overturn soil of the wall back can be reduced, and overturning resistance capability of the retaining wall is enhanced; the stress performance of the retaining wall is improved, and the manufacturing height of the wall is reduced, so that the aim of saving the material utilization amount of the wall is achieved; and meanwhile, the construction time is reduced, the direct economic benefits are achieved, and the method for improving the stress performance of the retaining wall and the retaining wall structure are suitable for being popularized.
Description
Technical field
The present invention relates to a kind of method and the retaining wall structure that improve retaining wall stress performance, belong to engineering construction technical field.
Background technology
Under the overall situation of construction land growing tension, new industrial working can get more and more in the situation of construction of sloping fields; The construction of hillside fields plant area generally all can relate to retaining wall, and the design of retaining wall, constructing can not be ignored the construction investment of plant area and security implication.The Normal practice of retaining wall is: the geologic information provided according to " report of engineering geological exploration ", according to Rankine or Coulomb theory, calculate topple soil pressure and overturning moment that retaining wall bears, select retaining wall material, shape, cross dimensions etc., check the abilities such as its bending resistance, shearing resistance, antiskid and overturning or slip resistance analysis by code requirement; When adopting Coulomb's earth pressure theory to calculate: active earth pressure Ea is the quadratic function that wall is high, when wall is high exceed certain altitude after (size of soil pressure depends on the slip soil wedge that wall is carried on the back, body of wall higher then soil wedge volume is larger, its soil pressure is also larger), the material usage of body of wall can increase significantly, can meet the stability requirement of body of wall slide and overturning or slip resistance analysis.In addition, while material increase, retaining wall construction period also can be adversely affected, and then directly affects the engineering construction cycle.
Summary of the invention
The technical problem that the present invention solves is: provide one can save materials for wall consumption, can ensure that again body of wall meets method and the retaining wall structure of the improvement retaining wall stress performance of slide and overturning or slip resistance analysis pressure stability requirements, to overcome the deficiencies in the prior art, it both decreased the engineering time, constructability, in turn save construction fund, be suitable for promoting.
A kind of method improving retaining wall stress performance of the present invention is achieved in that the method comprises retaining wall, landing slab is horizontally disposed with at the body of wall back side of retaining wall, and the length of landing slab is extended to the slide plane of wall back of the body slip soil wedge, the resistance to capsizing of topple soil pressure and the enhancing retaining wall of the retaining walls back of the body can be reduced like this, improve the stress performance of retaining wall.
Be: this structure comprises base plate 1, is arranged on the body of wall 2 on base plate 1, is provided with landing slab 3 in the back side horizontal direction of body of wall 2 that the length of landing slab 3 extends to the slide plane 4 of wall back of the body slip soil wedge according to of the present invention a kind of retaining wall structure that said method builds.
In above-mentioned retaining wall structure, landing slab 3 is arranged on 0.4 times of wall eminence on distance retaining wall top.
In aforesaid retaining wall structure, described body of wall 2 is L-type cantilever structures.
In aforesaid retaining wall structure, described body of wall 2 is buttress type structures.
Owing to have employed technique scheme, compared with prior art, enforcement of the present invention more for convenience, at the wall back side platform for making plate of conventional retaining wall, pressure reduction structure can be formed, the resistance to capsizing of topple soil pressure and the enhancing retaining wall of the wall back of the body can be reduced, improve retaining wall stress performance, reduce body of wall and make height, thus reach the object of saving materials for wall consumption, decrease the engineering time simultaneously, bring direct economic benefit, be suitable for promoting.
Accompanying drawing explanation
The schematic diagram of Fig. 1 to be body of wall of the present invention be L-type cantilever structure;
The schematic diagram of Fig. 2 to be body of wall of the present invention be buttress type structure;
Fig. 3 is the structural representation of conventional retaining wall section;
Being labeled as of accompanying drawing: 1-base plate, 2-body of wall, 3-landing slab, 4-slide plane, α-angle of rupture.
Detailed description of the invention:
Embodiments of the invention: the present invention includes the conventional retaining wall (as shown in Figure 3) built now, during enforcement, landing slab is built in the body of wall back side level of retaining wall, and the length of landing slab is extended to the slide plane of wall back of the body slip soil wedge, the resistance to capsizing of topple soil pressure and the enhancing retaining wall of the retaining walls back of the body can be reduced like this, improve the stress performance of retaining wall.
According to said method build of the present invention a kind of retaining wall structure structural representation as depicted in figs. 1 and 2, this structure comprises the base plate 1 of existing routine build and builds the body of wall 2 on base plate 1, during making, build landing slab 3 in the back side horizontal direction of body of wall 2, the length of landing slab 3 is extended to the another side of the slide plane 4(of wall back of the body slip soil wedge and the angle of rupture α of conventional retaining wall except horizontal direction).In order to realize best comprehensive benefit, namely while better improving retaining wall stress performance, material usage is minimum, landing slab 3 can be built 0.4 times of wall eminence on distance retaining wall top.In order to improve resistance to capsizing of the present invention further, described body of wall 2 can be built as L-type cantilevered (as shown in Figure 1).In order to improve resistance to capsizing of the present invention further, described body of wall 2 can be built as buttress type (as shown in Figure 2).
