Abstract :
Motuo is located in Tibet. It is the unique county without highway in China. Along ZaMo road are steep mountains with strong tectonic activity and seismic activity, broken rocks, plenty of rainfall. By calculating the stability coefficient, the stability coefficient of the K85 landslide was 1.03 in natural situation, which meant the slope was in creeping slip station. And saturation state was 0.95, meaning the slope was in unstable state. The stability coefficient was 0.82 in natural situation with effect of seismic intensity of IX degrees, which meant the slope was in unstable state. By contrast, recommend Anti-Slide Pikes in One Row, in combination of the Engineering of Water Drainage. While strengthening the monitoring, timely take appropriate emergency measures.
