Abstract

Steep slope, plenty of rainfall and broken rocks led to frequent debris flow along Zha-Mo Highway in Tibet, which badly destroyed highway structure and restricted the local economic development. We discover the distribution and characteristics of debris flow along Zha-Mo Highway after investigating and sampling typical debris flow. Debris flow is densely distributed with 80 points along the road, and density is 0.69 per kilometer. Owing to great difference of elevation (reaching up to 3000m) along the highway, the distribution density and genetic type of debris flow appear obvious vertical zonal. In addition, the debris flow along the route has the characteristics of wide graduation, angular grain, heavy big unit weight, poor clay and low viscosity. Thus, a typical geological disaster data catalog database query system was developed to query and retrieve geological disaster data for road engineers. The proposed system makes the highway disaster treatment more closer to the actual engineering demand.
