Research on Stability of Marlstone Slope by Different Excavation Methods
In order to improve the slump phenomenon of marl slope in highway engineering construction, the influence of different excavation methods of slope stability is determined by comparative analysis. Firstly, three excavation methods are simulated and analyzed by using the ABAQUS finite element software and drawing the stress-strain curve. Then, by comparing the displacement curves of the three excavation methods, the stress-strain distribution law caused by excavation is obtained. The soil reserved by the interval excavation method can restrain the slope deformation, especially the horizontal deformation of the vertical slope surface. Compared with the sequential excavation, the disturbance was smaller and the stability was better. Therefore, in order to avoid the instability of marl slope caused by unloading and rainfall after excavation, the method of interval excavation should be considered.
