Embodiment

[0024] Such as Figure 1-2 The test system for simulating the moving load of high-speed traffic in the present invention includes a load-bearing frame 1, a channel steel frame 2, plexiglass 3, a vertical loading frame 4, a moving loader 5, a forward moving loader 6, a reverse moving loader 7, Vertical loading beam 8 , mobile loading track 9 , vertical loading actuator 10 and support beam 11 . The model tank is composed of channel steel skeleton 2 and plexiglass 3, and a reinforced angle steel 12 is set in the middle of the model tank. The use of plexiglass 3 can facilitate the observation of the displacement of the soil and piles in the test; the model tank and the bearing frame are independently designed and processed, The model slot can be pushed into the carrying frame 1 by one end; the forward moving loader 6 and the reverse moving loader 7 can generate moving loads simulating high-speed traffic; the moving loader 5 can move at high speed in the moving limit rail 9 . Acco...

Abstract

The invention relates to a test system for simulating an action of a rapid traffic moving load. The test system comprises a bearing frame subsystem, a model slot system, a moving load loading device, a vertical loading frame subsystem and a vertical loading actuator, wherein the model slot system is mounted in the bearing frame subsystem; the moving load loading device is arranged in the model slot system; the action of the rapid traffic moving load is generated by the moving load loading device under the actions of a forward moving loader and a backward moving loader arranged at two ends of a moving load rail; the vertical loading frame subsystem is connected with the upper end of the bearing frame subsystem; one end of the vertical loading actuator is fixedly arranged on the vertical loading frame subsystem; and the other end of the vertical loading actuator is aligned with the moving load loading device and is used for simulating a vertical vibrating action of the traffic load. Compared with the prior art, the test system provided by the invention has the advantages that the moving action of the rapid traffic load can be simulated, the operation is convenient, the practicability is strong, and the like.

Description

technical field [0001] The invention relates to a test loading device in the field of traffic engineering, in particular to a test system for simulating the action of high-speed traffic moving loads. Background technique [0002] With the needs of social and economic development, the construction of my country's transportation infrastructure has entered a period of great development, and the construction of modern transportation facilities such as expressways has increased significantly, and presents the characteristics of large traffic volume and high frequency. For the pavement structure, the main function of the subgrade is to bear the wheel load transmitted by the surface layer and support the pavement structure. Under the repeated action of traffic load, due to the cyclic cumulative deformation of the soft soil foundation and the subgrade itself, the subgrade will settle. And lead to the destruction of the upper pavement structure, the settlement and uneven settlement o...
