Embodiment Construction

[0042] The present invention is described in detail below with reference to accompanying drawing and specific embodiment

[0043] A roadbed dynamic loading model test system is composed of a test box 1, two sets of reinforcement pile embedding devices 2, a loading device 3, and two sets of braking devices 4.

[0044] 1) The test chamber 1 consists of at least four steel pipe columns 1-1, two main side panels A1-2-1 arranged along the driving direction of the roadbed model, several auxiliary side panels A1-2-2, and a vertical roadbed model driving direction. Two main side plates B1-3-1 and several auxiliary side plates B1-3-2 arranged in the direction, two connecting channel steels 1-4 connecting the bottom ends of the two steel pipe columns 1-1 horizontally, embedded in the steel pipe column 1 -1 or the rubber pad 1-5 between the connecting channel steel 1-4 and the side plate B1-3. When the subgrade model 5-1 is longitudinally long, in order to prevent excessive deformation ...

Abstract

The invention discloses a testing system for a roadbed power loading model. The testing system for the roadbed power loading model consists of a testing box, two reinforcing pile build-in devices, a loading device, and two brake devices. The impact produced in the train dead load and running process is respectively simulated by a jack and a vibration exciter, a motor drives a model bogie to be moved on a model rail in high speed, and the action effect that carriages pass through the section of the roadbed successively can be simulated by using limited model bogies through the rationally setting the distance between the model bogies and the length of the model rail. The problem that the load cannot be moved while the train load is simulated by the linkage of the single-point excitation and multi-actuator is solved, the impact produced in the running of the train is considered so as to accord with the actual situation. The testing system can be used for testing the roadbed dynamic response under the heavy load train action and checking the reinforcement effect of the slant high pressure jet grouting pile for reinforcing the roadbed.

Description

technical field [0001] The invention mainly relates to the dynamic response of the subgrade under the action of the train load, in particular to a dynamic loading model test system for the subgrade. Background technique [0002] Heavy-haul railways have large transportation capacity and significant social and economic benefits. The development of heavy-haul railway transportation has become the main way for my country to accelerate the improvement of railway transportation capacity. On the other hand, as a large number of passenger dedicated lines have been put into operation one after another, the transportation capacity of existing lines has been released to a certain extent. After planned reinforcement and transformation of existing lines, the operation of heavy-haul railways can make full use of existing line resources and save money. [0003] Engineering practice in recent years has shown that it is feasible to operate heavy-haul railways after reinforcement and recons...
