Description
Technical field
The utility model relates to a kind of dynamic soil-pile interaction shaketalle test device of pile crown fixed end.
Background technology
At present, in dynamic soil-pile interaction earthquake simulation test, during the dynamic interaction response characteristic of simulation Integral Abutment supporting pile-soil structure under geological process, stake and bridge abutment structure often replace with articulated form, the force-transfer characteristic of real Integral Abutment supporting pile and superstructure consolidation form can not be reacted, therefore can not support the dynamic interaction characteristic of oil and pile by accurate response beam front axle beam bridge platform.
Secondly, this type of shock test belongs to one of large-scale dynamic test, pointed strong, the high reliability of this type of test.But its cost is higher, the data as an external experiment fees show, and when carrying out shaking table model test, expense hourly is even up to millions of dollars, and whether the way of image data accurately and is comprehensively directly connected to the win or lose of test.Therefore design one can real simulation stake-Tai consolidation, data acquisition convenient, comprehensively dynamic soil-pile interaction shaketalle test device and construction method significant.
Summary of the invention
Technical problem to be solved in the utility model can not support dynamic soil-pile interaction and can not the problem of hazard to bridge's pier end anchorage force and horizontal shift in acquisition test process comprehensively by real simulation beam front axle beam bridge platform for the hinged pile crown consolidation likeness in form of above-mentioned conventional belt, provides a kind of dynamic soil-pile interaction shaketalle test device and construction method thereof of pile crown consolidation.
Specific embodiments of the present utility model is: a kind of dynamic soil-pile interaction shaketalle test device of pile crown fixed end, involving vibrations platform table top, test pile, sandy soil case, abutment and attachment strap, described vibration table surface is provided with test pile, described test pile is placed in sandy soil case, the vibration table surface of described test pile both sides is respectively provided with sleeper beam, described abutment is fixedly connected with test pile with attachment strap lower surface, the sleeper beam top of both sides arranges a horizontal shift load transducer and vertical load sensor respectively, described horizontal shift load transducer and vertical load sensor contact with attachment strap with abutment.
Further, balancing weight is placed on described abutment top.
Further, described test pile is consolidated at the bottom of sandy soil case case, and exceeds sandy soil box top test pile 1/6 height.
Further, described abutment and attachment strap are integrated.
Further, described vertical load sensor is placed in sleeper beam top and supports attachment strap, and described horizontal shift load transducer is fixedly connected with attachment strap through a cross bar.
Compared with prior art, the utility model has following beneficial effect: the dynamic soil-pile interaction shaketalle test device of this pile crown fixed end, by Optimal Experimental model structure, well solves this type of test unit conventional and can not support dynamic soil-pile interaction and can not the weak point of hazard to bridge's pier end anchorage force and horizontal shift etc. in acquisition test process comprehensively by real simulation beam front axle beam bridge platform.Especially its load measurement meter simulation attachment strap end sleeper beam supporting role utilizing support and intermal force to be integrated and measurement vertical load, the sleeper beam top of the another side of described sandy soil case is provided with the transmission rod device measuring abutment horizontal shift and power in addition, its lithe, solve the problems such as Test Data Collecting is loaded down with trivial details, and this test unit can utilize sleeper beam to support attachment strap end, make process of the test abutment remain level, thus the internal force generated in pile crown and abutment junction conform to more with actual conditions.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-vibration table surface, 2-sandy soil case, 3-test pile, 4-sleeper beam, 5-horizontal shift load transducer, 61-abutment, 62-attachment strap, 7-balancing weight, 8-vertical load sensor.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, sandy soil case 2 is placed on vibration table surface 1, and the work top 1 sleeper beam 4 being placed in each both sides of sandy soil case 2 is to study abutment one-piece construction anti-seismic performance.Diagram test pile 3 upper end is goed deep into abutment inside and is consolidated in the true stress performance of one simulation beam front axle beam bridge platform supporting pile.Wherein abutment 61 and attachment strap 62 are in one, and during by shake vibration, attachment strap 62 entirety moves horizontally with abutment 61.
In the present embodiment, described test pile 3 is consolidated at the bottom of sandy soil case 2 casees, and exceeds 1/6 height of sandy soil case 2 top test pile 3.
Described abutment 61 is fixedly connected with test pile 3 with attachment strap 62 lower surface, sleeper beam 4 top of both sides arranges a horizontal shift load transducer 5 and vertical load sensor 8 respectively, described vertical load sensor 8 is placed in sleeper beam 4 top and supports attachment strap, vertical load sensor 8 and attachment strap 62 level are to motion, play again the effect of measuring attachment strap 62 one end vertical supporting power, horizontal shift load transducer 5 is fixedly connected with through a cross bar can measures horizontal shift and horizontal force simultaneously with attachment strap 62.
Diagram balancing weight 7 can be built according to specific needs and be fixed in abutment top, and balancing weight 7 Volume design is less, convenient applying and unloading.
During use, utilize the vibrations of shaking table thus realize with study portion bridge abutment structure seismic performance or research abutment one-piece construction anti-seismic performance.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
