Description
Technical field
The invention belongs to technical field of civil engineering, particularly high-grade highway deep soft soil foundation settlement after construction control panel holds formula embankment technology.
Background technology
There is a large amount of soft soil foundations in the coastal interior ground lakeland that reaches of China; Building highway, high-speed railway, river dike etc. on soft soil foundation; Need handle soft soil foundation, with control settlement after construction (being the sedimentation that in a period of time in 10 ~ 15 years of overhaul, produces after embankment puts into effect).For high-grade highway, the settlement after construction control of general highway section requires to be 30cm that the end of the bridge highway section is 10cm.Settlement after construction control method for deep soft soil foundation generally has two types: one type is consolidation, like preloading, vacuum method, precipitating, pre-pressing method etc., generally needs to combine vertical plastic draining board as drainage channel; Another kind of is compound foundation method, can be subdivided into flexible pile composite foundation and rigid pile composite foundation method again.Flexible pile such as cement mixing method (slurry, wet shot stake), sand pile and broken stone pile etc., rigid pile has the CFG stake, pile for prestressed pipe (PHC stake) and cast-in-situ concrete large-diameter tubular pile (PCC stake) etc.Draining preloading technology maturation, construction is simple, can handle the soft base of depth more than 20 meters; But its main deficiency is that the precompressed processing time is long, and it is bigger to handle the back settlement after construction, and the compensation earth volume is big; And an operation way of escape levee crown reparation compensation cubic metre of earth meeting produces new load, causes new sedimentation again.Flexible pile composite foundation is generally handled 15 meters of below grounds only with interior soft foundation, should not be used for the deep layer processing soft soil, and in reinforcing scope because the flexible nature of stake, its pile body still has sedimentation to produce.Rigid pile such as CFG are to handle one of feasible method of deep layer weak soil, and generally about 50 centimetres, pilespacing generally is not more than 1.5 meters in the stake footpath, and consolidation effect is good, but ground processing cost is very high.For the high-grade embankment on the deep soft soil foundation, owing to be a kind of flexible load, so after adopting above-mentioned processing method to carry out reinforcing soft foundation; The subsidiary stress at embankment center and embankment edge varies in size; The subsidiary stress at embankment center is greater than the embankment edge, makes that the settling amount at embankment center is bigger than embankment edge, thereby makes the face of land produce the differential settlement of " the bottom of a pan " shape; Cause highway to produce longitudinal crack when serious, the comfortableness and the safety of influence driving.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, provide that a kind of cost is low, quick construction, settlement after construction high-grade highway deep soft soil foundation settlement after construction control panel little, that do not produce " the bottom of a pan " shape differential settlement hold formula embankment technology.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
A kind of high-grade highway deep soft soil foundation settlement after construction control panel holds formula embankment technology, between soft foundation and embankment filled soil, armored concrete slab is set as crust layer, and it is characterized in that: concrete slab thickness is 300mm ~ 1000mm; Concrete slab can be positioned on the face of land, or partly imbeds ground, or all imbeds ground; Bed course can be laid in the concrete slab bottom; The gradient of embankment filled soil is steeper, and the slope ratio is less than 1:1.5, and domatic employing geotextiles is wrapped up; Concrete slab can be provided with low barricade near the embankment both sides of edges; Concrete slab is provided with the shrinkage joint in the road Cross Section direction; The concrete slab variable thickness.
The material that bed course is laid in said concrete slab bottom can be rubble, graded sand and stone, building masonry rubbish etc.
Said embankment filled soil is divided into multistage filling, domatic one deck geotextiles parcel that adopts respectively that each grade bankets.
Said barricade is vertical with concrete slab, and is fixed together with concrete slab, bulk deformation, and wall height is not more than the embankment filled soil height.
Said shrinkage joint should be arranged on the depth of fill and geological conditions changes little position, cross section, and the shrinkage joint direction is vertical with the road travel direction.
Said concrete slab can be along the variation adjustment thickness of road direction according to geological condition, thickness of slab attenuation when foundation soil is hard, thickness of slab thickening when foundation soil is softer.
The embankment filled soil on said concrete slab top can be selected light material for use, like EPS particle light mixed soil, bubble lightweight composite soil etc., alleviates the embankment deadweight, with concrete slab acting in conjunction compatible deformation, controls Embankment Subsidence better.
Advantage of the present invention and effect are:
On the soft foundation, the armored concrete slab of rigidity is set under the embankment filled soil; Therefore the bending rigidity of armored concrete slab itself is very big, is out of shape for a short time, has eliminated the relative settlement at embankment edge and embankment center; Make the whole evenly sinking of embankment, avoided roadbed to produce longitudinal crack.
Through concrete slab is partly or entirely imbedded ground, lay bed course in the concrete slab bottom, bearing capacity of foundation soil can be met the demands, and convenient construction.
Course can adopt building waste, has played the effect of environmental protection.
Because concrete slab intensity is very high, so unstable failure can not take place in side slope of embankment, and side slope is steepening suitably, and barricade perhaps is set, thus the side that has reduced embankment filled soil measure, saved construction costs.
In the concrete slab both sides barricade can be set, the fixing integral body that forms of barricade and concrete slab, the wall of barricade receives the effect of soil body lateral pressure, and the concrete slab generation top bottom making is drawn, the moment of flexure of bottom pressurized; The soil pressure that acts on concrete floor then produces the moment of flexure that concrete slab generation upper portion pressurized, bottom are drawn, and both just in time cancel out each other, and make the amount of deflection of concrete slab and stress all less.In addition, it is more even that barricade can make top banket, and keeps stress balance on the base plate, is equivalent to evenly distributed load.
Adopt rigid slab to replace conventional method for processing foundation, make the embankment flexible load become rigid load, produce bulk deformation, the indifference sedimentation does not need ground to handle and eliminates relative settlement, has therefore saved expensive ground disposal cost.
Compare with consolidation, the present invention is because discharging consolidation is slow, behind the worker in the certain hour sedimentation little, promptly settlement after construction is little.Compare with compound foundation method, cost of the present invention is low.Duration of the present invention is short, only considers to banket the duration, and particularly suitable is with general highway section on the deep soft soil foundation.
