Zonaion of Danger Degree of Geological Hazards over Lanzhou-Chengdu-Chongqing Products Pipeline

The paper takes geological hazards over Lanzhou-Chengdu-Chongqing Products Pipeline as a study objective. Through analysis to the existing geological data and field investigation, the authors utilize the method of integrated index and systemically analyze the basic factors of geohazards development, the exterior factors of inducing geohazards as well as present situation, to regionalize the danger degree of the areal geohazards over the pipeline and the geohazards along the pipeline. The result of zonation is in good consistency with the existence of geohazards.
