Abstract

Based on the numerical simulation method, a research on the optimal design of cutting and excavation control was conducted for Zhonglou Mountain Landslide in North Shaanxi, China. Three excavation slope angles, namely, 53ø, 54ø and 55ø, were chosen for numerical simulation calculation and comparative analysis under the condition of long-period rainstorm. The results of analysis show that the excavation slope angle of 55ø is relatively dangerous under the condition of long-period rainstorm; the excavation slope angle of 54ø can save an excavation volume of 41.19m3 per meter of width compared with the angle of 53ø, and it is also safer and more stable. Therefore, it is concluded that the angle of 54øis the safest and most economical excavation slope angle for cutting and excavation control. The above method provides technical reference for control of similar landslides and also has certain scientific value and practical significance in engineering.
