Sichuan-Tibet Highway traverses the two principal geomorphic units and theirtransition belt in western China; it has some hazardous slopes characterized by highaltitude and chilliness, high elevation, large scale and complexity. Various hazardsusually concur in groups. The integrated hazards of these slopes cannot be reflected byany single hazardl they act on one another and develop at the same time, like many otherthings experiencing a recurrent evolving course from growth to demise. Based on themechanisms of the typical dangerous No.1 slope of Erlang Mountain on theSichuan-Tibet Highway, various simulations through geotechnical test, numericalcalculation, and in-situ monitoring have been carried out to control and regularize the lastphase of evolution of the slope. The text shows that such slopes have developed undergeological and engineering conditions that might have enforced the potentiality of hazards; interactions between different hazards are of more menace than any single factor;structures in cooperation with the hazardous bodies may be effective for preventing such calamities.
