Description
Technical field
The utility model relates to a kind of structure and is applied to slope soft foundation embankment structure in the engineerings such as railway, highway, municipal administration, airport.
Background technology
Hills and mountain region account for 60% of Chinese area, fill the cubic metre of earth and stone on the slope, are one of engineering problems very general in the civil engineering construction.Embankment engineering in slope according to slope land basement rock soil feature, can be divided into general slope embankment engineering and slope soft foundation embankment engineering.Soft foundation embankment engineering in slope refers to ground base system weak rocks soil, and bearing capacity is relatively low, under the load action that bankets, ground can produce big horizontal distortion, and the safety problem of embankment engineering mainly is horizontal distortion and the downslide unstability of embankment together with ground except that the embankment slope stability.
The slope soft foundation is a kind of special slope ground, it is characterized in that the ground top layer is weak relatively, and foundation surface or soft layer bottom has certain cross fall, under the embankment load action, soft layer produces the lateral deformation of directed downwards one side when producing compressive strain, concentrate the ground middle part different with horizontal soft foundation soft layer distortion, slope soft foundation soft layer distortion concentrates near the one side slope pin of below, the shearing strain meeting of below one side slope pin ground is bigger, the easier foundation instability that causes.
Soft foundation embankment structure in slope is in railway, highway, municipal administration, the airport construction as the existing practical problem of embankment engineering such as embankment, the piece of smooth land and proposing, and it can not simply regard the two comprehensively simple of soft foundation and slope ground as.At present, more to the research of horizontal soft foundation (soft foundation) embankment structure both at home and abroad, less to the research of slope ground embankment structure, and be limited to general slope ground more, the research of slope soft foundation structure is reported particularly lack.Engineering practice shows, fills the cubic metre of earth and stone on the soft foundation of slope, easily produce ground and embankment engineering and destroy, and be the outstanding weak link in mountain railway, the highway engineering construction.
In slope soft foundation embankment engineering, as adopting the technical measures that in level is flabbiness ground strengthened, adopt usually, as gravel pile reinforcing structure, composite foundation structure etc., although can improve the stability of slope soft foundation embankment to a certain extent, but its bearing capacity in, can't guarantee that the unstability disease does not take place ground.Therefore, adopt at present usually at the slope soft foundation and to change the made ground base or with the method for bridge for the road, this certainly will cause engineering quantity to increase, be unfavorable for control, reduce construction costs.
The utility model content
Technical problem to be solved in the utility model provides a kind of safe and reliable, economical and practical slope soft foundation embankment structure, and it can avoid the generation of unstability diseases such as slope soft foundation embankment, the piece of smooth land effectively.
The technical scheme that its technical problem that solves the utility model adopts is: slope of the present utility model soft foundation embankment structure, comprise the embankment layer that fills on the slope soft foundation that constitutes by hard basal layer and soft layer, it is characterized in that: described embankment layer toe lower edge longitudinal separation is arranged with anchor pile, and it is fixed with hard basal layer that anchor pile passes soft layer.
After taking abovementioned technology, because anchor pile forms lateral restraint to soft layer near a side slope pin below the soft layer, shearing strain is controlled in the scope of permission, therefore can avoids the generation of unstability diseases such as slope soft foundation embankment, the piece of smooth land effectively.
As a kind of preferred version of the present utility model,, also has the ground stabilization structure in the described soft layer for further improving the stability of slope soft foundation embankment structure.
As a kind of preferred version of the present utility model, for guaranteeing the stability of slope soft foundation embankment structure, described anchor pile can divide two rows to lay along the lateral separation of embankment layer.
The beneficial effects of the utility model are, can avoid the generation of unstability diseases such as slope soft foundation embankment, the piece of smooth land effectively, can guarantee the smooth construction of slope soft foundation road embankment, avoid the loss of engineering and lives and properties.With change the made ground base or compare with technical measures such as bridge Dai Lu, can reduce engineering quantity and construction costs significantly.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
See figures.1.and.2, slope of the present utility model soft foundation embankment structure, comprise the embankment layer 20 that fills on the slope soft foundation that constitutes by hard basal layer 10 and soft layer 11, described embankment layer 20 toe lower edge longitudinal separation are arranged with anchor pile 21, and it is fixed with hard basal layer 10 that anchor pile 21 passes soft layer 11.Because anchor pile 21 forms lateral restraint to soft layer near a side slope pin below the soft layer, shearing strain is controlled in the scope of permission, therefore can avoid the generation of unstability diseases such as slope soft foundation embankment, the piece of smooth land effectively.
In the embankment construction of slope soft foundation, described anchor pile 21 can be arranged by one usually and be established (seeing figures.1.and.2), big or soft layer thickness is bigger as the gradient, then can divide two rows to lay (with reference to Fig. 8), to guarantee the stability of slope soft foundation embankment structure along the lateral separation of embankment layer 20.
According to the concrete condition of slope soft foundation, also can carry out consolidation process to soft layer 11, promptly, improve the stability of slope soft foundation further by lateral restraint anchor pile 21 is combined with existing ground stabilization structure.Combination has following several types usually: with reference to figure, described ground stabilization structure is the gravel pile reinforcing structure 22 that is provided with below embankment layer 20 toe; With reference to Fig. 4, described ground stabilization structure is to reinforce structure 23 at the discharging consolidation that embankment layer 20 toe one side is provided with; With reference to Fig. 5, described ground stabilization structure is arranged on the replacement stone pile composite foundation structure 24 between 20 times top layer of embankment layer and the hard basal layer 10; With reference to Fig. 6, described ground stabilization structure is arranged on the DJM pile compound foundation structure 25 between 20 times top layer of embankment layer and the hard basal layer 10; With reference to Fig. 7, described ground stabilization structure is the pile foundation joist retaining wall structure 26 that is consolidated in anchor pile 21 tops.
Some principles of the above the utility model slope soft foundation embankment structure that just explains through diagrams, be not be the utility model slope soft foundation embankment structure to be confined to shown in and in the described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
