Description
Technical field
The invention belongs to the technical field of long stake Research on Nonlinear Dynamics, and in particular to the preferable single pile response of one kind simulation
Fixation and loading system.
Background technology
At present, pile foundation is used widely as a kind of deep foundation form in engineering, simultaneously because place and load etc.
Condition it is complicated various, the application of long stake and ultra-long pile in engineering is also increasing year by year.Because the length of long stake or ultra-long pile is thin
Than larger, it is easier to occur dynamic buckling for stub or causes self structure to be destroyed because deformation is excessive.Rung in power
Should during, pile foundation is as an energy transmission between superstructure and basis and the bridge undertaken, its dynamic characteristics and stake
The security performance of base is just particularly important.Therefore the dynamics research of long stake is just by very big attention.In order to more accurate
Model engineering it is actual and study the dynamics problem of long stake, the construction of the actual experimental provision of a laminating is experimental study essence
The basis being really smoothed out.
The content of the invention
It is an object of the invention to provide a kind of fixation and loading system for being used to simulate preferable single pile response, to simulate ideal
The nonlinear kinetics response of single pile.
In order to solve the above technical problems, the technical solution adopted in the present invention is：One kind is used to simulate preferable single pile response
Fixation and loading system, including fixed cylinder, fixed platform and extension spring, single pile is vertically arranged in fixed cylinder, fixed circle
The side wall of cylinder is circumferentially equidistant to open up fixing hole, and to install extension spring, extension spring one end is fixed on fixing hole, and the other end is fixed on single pile
On；Described fixed platform has the platform panel for being arranged on fixed cylinder upper end, and platform panel stretches out the part of fixed cylinder
Supported by supporting leg, the vibrator to apply horizontal load to single pile pile body is arranged on the sleeper of fixed platform, vibrator
It is connected with single pile.
Further, the fixed cylinder is divided into two layers up and down connected by round flange, and each layer is by two semicircular cylinders
Docked by straight flange.
Further, vertical ribbed stiffener and ring ribbed stiffener are set on the outside of the fixed cylinder.
Further, the platform panel sets U-shaped breach with the adjacent side of Single Pile body phase, passes through for pile body.
Further, the extension spring is made up of spring, drag hook, screw rod, and drag hook and screw rod are separately positioned on the two ends of spring,
Screw rod is fixed on by nut on the fixing hole of fixed cylinder, and drag hook is connected with single pile pile body.
Compared with prior art, the beneficial effects of the invention are as follows：
First, the present invention utilizes multiple equally distributed extension springs to simulate the stress of the soil layer in foundation ditch around long stake, using sharp
The device that shakes produces the horizontal load of change, can preferably study non-linear dynamic of the long stake when being changed by horizontal load and ring
Should, provide reference for the construction of engineering.
Second, because the diameter of fixed cylinder is smaller, therefore, for the ease of the installation of extension spring in fixed cylinder, fixed circle
Cylinder is made up of two layers of connection up and down, so when being installed, first the fixation cylinder of lower floor and extension spring can be installed, so
Carry out the installation on upper strata again afterwards.
