Risk analysis system for highway bank slope hazard from water action of reservoir

Through the characteristic analysis of linear engineering,this paper,above all,brings forward the conception of linear assessment(or band assessment) aimed at the risk analysis of large-scale linear engineering,and at the same time analyzes its meaning in detail.Then it takes highway bank slope as the typical example of this kind of large-scale engineering,and puts forward the basic definition of the risk analysis of highway bank slope hazard by the action of water in the reservoir.And at one time,combined with the different purposes,assignments,demands,etc.in different phases of reconnaissance,it still clarifies the characteristics of linear assessment and established its theory system of risk analysis.Finally,through the research on the types of bank slope hazard and the characters of hazard-affected body,it founds the correlated evaluating indicator system of hazard and vulnerability,and in the meantime it also preliminarily studies on the risk control system of the bank slope hazard.
