Study on the Performance of Reinforced Embankment on Mountain Slope Using Full-Scale Model Experiments

Abstract

The full-scale model test is used to study the stability and deformation control of reinforced sloped embankments on mountain slope foundation. According to practical experience in the expressway construction in the mountain region, two full scale model experiments were carried out in laboratory. One model is reinforced by geogrid and the other is un-reinforced in the embankments. The design of the model, test data and analysis methods are emphatically introduced. During the experiments, some key test data were monitored, such as the vertical and horizonal displacements distribution of slope, the vertical displacement on the top of the embank, the internal stress and displacement distribution, the form and position of the slip curve surface in the two embankments. Comparing experiment of reinforced with un-reinforced, it shows that the lateral displacement of embankments of the former is smaller and the stability of embankments is higher than that of the latter. The model experiment results can give reference for the construction of China's western mountain highway.
