Characteristics of an ANCI Landslide in Bailongjiang River Basin and Evaluation of Control Measures

The Xieliupo landslide is an ancient landslide controlled by tectonic faults and triggered by earthquakes. It is located on the southern side of Gansu Province, on the right bank of the Bailong River. The landslide is underlain by the disaster-prone strata of the Bailongjiang Group phyllite. Affected by heavy rainfall, it has developed numerous fissures, and has been continuously creeping and even experienced several phases of significant sliding. Based on experimental testing, unmanned aerial vehicle (UAV) measurements, and other methods, the physical and mechanical properties of the rock and soil mass of the Xieliupo landslide have been obtained. A numerical simulation model was established to analyze the stability of the landslide and to evaluate the effectiveness of the prevention and control measures.
