Description

Tiltedly orthogonal is for a clump of piles - Soil - Structural interaction experimental model
Technical field
The invention belongs to geotechnique's similarity simulation experiment technical field, be specifically related to a kind of similarity simulation experiment model, particularly relate to oblique orthogonal for group's Pile-soil-structure Interaction experimental model.
Background technology
At present, oblique orthogonal is widely used in the Long Span Roof Structures public building bases such as highway bridge, port and pier, offshore drilling platform, high-filled embankment, high tower structure, high-rise building, pattern foundation pit supporting structure, basement process, large-scale electric power line pole tower and airport, stadiums, recreational and sports activities center, exhibition center for a clump of piles.Although recent domestic has carried out some Pile-soil-structure Dynamic Interaction model investigations, and achieve more achievement in research, but these researchs are all carried out for vertical single pile or a vertical clump of piles, corresponding experimental model is vertical single pile experimental model or vertical clump of piles experimental model, yet there are no the oblique orthogonal documents and materials for group's Pile-soil-structure Interaction experimental model both at home and abroad.
Stress and the deformation characteristic of group's Pile-soil-structure Interaction system is replaced in order to study oblique orthogonal, under the subsidy of project of national nature science fund project (numbering: 41372288), intend using similar simulation experimental method to carry out correlational study, but owing to oblique orthogonal makes complexity for group's Pile-soil-structure Interaction experimental model, so that still lacking the similarity simulation experiment model matched at present, accordingly, it would be desirable to a kind of effective tiltedly orthogonal of invention is for group's Pile-soil-structure Interaction experimental model.
Summary of the invention
It is an object of the invention to provide a kind of tiltedly orthogonal for group's Pile-soil-structure Interaction experimental model, this experimental model not only can reflect the oblique orthogonal interaction property for group's pile-soil-structure system really, and simple in construction, cost of manufacture are cheap, practical, Technological Economy is feasible.
The technical solution used in the present invention is: tiltedly orthogonal is for group's Pile-soil-structure Interaction experimental model, and it is made up of for multi-column pier foundation, cushion cap and superstructure soil case, foundation soil, oblique orthogonal;Described native case is hollow cuboid open above, Plate Welding form;Described foundation soil is divided into two-layer, and upper strata is clay, and lower floor is sand;Described oblique orthogonal is made up of two plumb piles and two raked piles for multi-column pier foundation, and at the bottom of stake, absolute altitude is identical;Described cushion cap is the cuboid of concreting, and plumb pile and raked pile are joined for entirety by it;Described superstructure is made up of Single column pier and counterweight, and Single column pier is cylinder, and two vertically disposed threaded rods are implanted in upper end, and counterweight is combined by the counterweight of Different Weight.
The construction usage method of the present invention is: tiltedly orthogonal is for group's Pile-soil-structure Interaction experimental model, first, according to the prefabricated overall structure being made up of for two plumb piles in multi-column pier foundation and two raked piles, cushion cap and Single column pier oblique orthogonal of design size, and implant two vertically disposed threaded rods in the upper end of Single column pier.Then, require to weld soil case according to design with steel plate, and fill out the sand in foundation soil in soil case, when an absolute altitude at the bottom of the depth of fill reaches, the prefabricated overall structure being made up of for two plumb piles in multi-column pier foundation and two raked piles, cushion cap and Single column pier oblique orthogonal is placed to by design requirements the top of foundation soil, then continues back-up sand native, when the depth of fill reaches the designed elevation of sand, start to fill out clay, until the depth of fill reaches the height that design requires.After experimental model completes, according to the load of superstructure needed for experiment, choose the counterweight of Different Weight required for counterweight, and the counterweight chosen is placed on the threaded rod of Single column pier upper end, add Upper gasket, fastening nut.Finally, experimental requirement, oblique orthogonal is carried out loading experiment for group's Pile-soil-structure Interaction experimental model, and records relevant experimental data.
The operation principle of the present invention is: tiltedly orthogonal is for group's Pile-soil-structure Interaction experimental model, it is the reduced scale experimental model being made according to the pre-determined likelihood ratio, the composition structure of this experimental model is all consistent with Practical Project with stressing conditions, therefore, it can reflect really that in Practical Project, oblique orthogonal replaces stress and the deformation characteristic of group's Pile-soil-structure Interaction system.
The invention has the beneficial effects as follows: tiltedly orthogonal is for group's Pile-soil-structure Interaction laboratory model construction is simple, easy to make, cheap, engineering practicability is strong, and can comprehensive and accurate simulation Practical Project situation, gained result of study can truly reflect that in Practical Project, oblique orthogonal is for the mechanical state of group's Pile-soil-structure Interaction system, thus theory analysis, engineering design and the site operation for Practical Project provides necessary data support and construction to instruct.
