Abstract

The invention provides a combined variable cross-section roadbed compaction model simulation device. The device comprises combined model channel steel plates, a multifunctional loading device, a functional layer, a monitoring device and a signal acquisition and processing device. The device has the beneficial effects that the combination of the combined steel plates can achieve model tests of model grooves with different section widths and scales, the change of the height and the inclination angle of the lateral steel plates can achieve the simulation of different roadbed supporting and retaining structure forms; the multifunctional loading device can meet load loading requirements of different forms, and the combined variable cross-section roadbed compaction model simulation device is provided with the functional layer, the monitoring device and the signal acquisition and processing device to form a complete road compaction simulation system; and according to the invention, the road on-site compaction process is simulated through an indoor test, the compaction degree is monitored, the compaction quality is judged, and the combined variable cross-section roadbed compaction model simulation device has important significance for improving the road compaction mechanism and the compaction performance.

Description

technical field [0001] The invention relates to the technical field of road engineering, in particular to a combined variable-section subgrade compaction model simulation device. Background technique [0002] Since 2000, the scale and speed of road construction in my country have developed rapidly. By the end of 2018, the total mileage of my country's highways will exceed 4.8 million kilometers, ranking first in the world. With the improvement of my country's road transportation system, the proportion of heavy-duty traffic in the road is increasing, and the emergence of heavy-duty traffic has put forward high requirements for roadbed compaction, road surface material selection, and construction technology. In order to adapt to the increasing proportion of heavy-duty traffic, the compaction quality of road construction needs to be further controlled and optimized. [0003] The geological conditions of different road construction environments are also different, and differen...
