Description

A kind of method of punishing loess slope medium bed disease peeling
Technical field
The present invention relates to the slope project technical field, especially relate to a kind of method of punishing loess slope medium bed disease peeling.
Background technology
In the reality, the loess slope disease peeling can be divided into three classes by exfoliation layer thickness: the top layer skinning peels off, middle level bed separation and thick-layer slump shape peel off.
Wherein, the main feature that the top layer skinning peels off is: thickness is generally between the 3-5cm, and in the form of sheets, closely round shape, trapezoidal shape etc. peel off skinning, often appear in the strong yellow soil, form because of reasons such as weathering, freeze thawing, sourings usually.
The main feature of middle level bed separation is: bed separation thickness in middle level is 10~40cm, the general in appearance curved or rectangle of incrustate, and scale is generally (1.0~1.5m) * (2.0~4.0m); Be wedge shape on the whole, last thick thin down, the thick about 10~20cm in top, bottom thickness is less than 10cm; Exfoliation layer is smooth and more smooth, upwards grows and delays in former domatic along domatic from toe.The chunk shape peels off generally larger, and the domatic complete sum of heavy damage is stable, and the soil body integrality of peeling off is better, is bulk and is deposited on toe or the platform, stops up gutter (gutter).The disease peeling great majority that Huang prolongs loess slope are this type.
The main feature that thick-layer slump shape peels off is: thick-layer slump shape peels off general scale and differs, and is similar to avalanche, and the motion mode of incrustate is slippage, avalanche.Its thickness is 50~80cm, influenced by joint fissure, and the face form of peeling off is controlled by joint plane.In the practice, exfoliation layer thickness is greater than being usually said avalanche phenomenon greater than the situation about 80cm, and then corresponding employing is handled at the improvement method of avalanche.
Nowadays, about loess slope disease peeling punishment technology, also there is not a cover mature technique standard to instruct.From general status, the safeguard procedures that some emphasis circuits of loess area have all adopted some to suit measures to local conditions more or less.At present, at the domatic guard technology of loess slope, mainly contain following several:
One, people's work post grass bank protection, this protection can be divided into ditch kind, cave kind, sow seeds, turfing and plant modes such as giving birth to band.This kind guard technology is better to the protection effect of surface layer peeling, but the protection effect that peels off for middle level or thick-layer is relatively poor; For the soil is porous, the soil body on slope protection works top, cause that owing to hitting to spatter to corrode gravity-type peels off, finally lose prevention effect.With cave kind punishment loess slope medium bed disease peeling is example, the place that slope protection works is arranged for the side slope bottom, during rainfall, raindrop will hit above slope protection works, because of the raindrop that splash have certain strike and undercutting to domatic loess, form counter-slope the most at last, therefore will form disease peeling under action of gravity, this moment, kind protection in cave lost effect; Occurred new peeling off simultaneously, this is because the thickness that the root system of plant that the cave kind forms declines and destroys less than the soil body, thereby has lost protection effect.
Two, alien earth sparging, loess is domatic in the domatic back of sowing grass seeds by duster is covered by grass planting, and grass planting grows fine, slope leveling, no peeling phenomenon takes place.But because the reinforcement depth of alien earth sparging root system of plant is in scope the best of 0.2-0.3m, thereby effect is relatively poor when handling the thick-layer disease peeling.Prolonging highway with Huang is example, the alien earth sparging punishment section of being completed in March, 2007, and when obtaining more satisfactory vegetation planting effect every year, coverage scale can reach 75%; The phytobiocoenose of new planting can be smoothly by survive the winter, summer more, can stand winter severe cold with summer the hot summer weather arid ecological environment test.But in July, 2008 investigation finds, because the reinforcement depth of alien earth sparging root system of plant is in scope the best of 0.2-0.3m, thereby occurred new peeling off again.
Three, geotechnical grid, this kind method peel off effect in punishment loess slope top layer and middle level better, and it is unsatisfactory that thick-layer is peeled off effect, and cost is higher.
Four, complete domatic dirty worker's protection, this method will be sealed the growing environment of plant, make forever to recover the natural vegetation of excavating destruction because of expressway construction.
Five, skeleton grass planting bank protection, this means of defence are applicable to the side slope that the gradient is slow, and the slope of general treated side slope is than less than 1: 0.75, and is relatively poor to the loess slope disease peeling effect that the gradient is steeper.
