Abstract
Debris Flow Hazard Assessment along the Tianshan Highway was carried out
based on an established model. The assessment results indicated impacts of
debris flow hazards to the highway and supplied a quantitative index with
highway construction designs and protection in the debris flow affected area.
The model formula can be shown as: S=K1K2; here S is highway debris flow
hazard degree, K1 is debris flow hazard degree (0 ≤K1 ≤1), K2 is highway
damage degree (0 ≤K2 ≤1). Index K1 as well as K2 are obtained with quantitative
calculations respectively. This model has been verified based on research on
highway debris flow in the Tianshan Mountain area of Xinjiang in China.
Keywords: highway, debris flow, hazard degree, assessment model.
1 The idea of highway debris flow hazard degree assessment
model
The debris flow in the Chinese Xinjiang's Tianshan mountainous area is one kind
of serious natural disaster, which can interrupt the transportation on road, destroy
the highway facilities, even create serious traffic accidents frequently [1].
Current domestic and foreign debris flow risk factor assessment models only
can appraise debris flow gully to the natural degree and are unable to evaluate
the road safety rate. In order to appraise the debris flow effectively to the
highway harm degree, meet quantitative factors [2] and instruct the highway
design and maintenance, we set up the following highway debris flow hazard
degree assessment model.
S=K1K2 (1)
Keywords
highway, debris flow, hazard degree, assessment model.
