Other Abstract



The engineering geological condition along the Lengqu River section of Sichuan - Tibet Highway is extremely poor and complicated. Rich geological hazards developed along the Lengqu River section is posing a direct threat to the Highway safety and compromising improvement project of the Highway.It's extremely imperative to investigate the engineering geological condition for the sake of the Highway improvement project.By analyzing engineering geological conditions,a qualitative engineering geological evaluation and zonation was completed in terms of differences in engineering geological conditions at highway sections; Some governing factors-slope,surface rolling,internal friction angle and cohesion of rock,density and activity of fault,exogenic geological process and hydrogeological conditions-were selected as evaluation indices; Then a hierarchical model was introduced and weight of each factor was determined properly. Quantitative engineering geological evaluation was performed according to Engineering Geological Index and Set Pair Analysis method.Reasonable results was acquired after comparison of preliminary and quantitative evaluation as well as verification of disaster distribution. The referred area was divided into 3 zones and 6 subzones,and a sketch of engineering geological zonation was drawn to serve engineering renovation,disaster prevention and reduction.
