Plateau Gardient Zone Highway Eatrhquake Contorl And Emergency Rescue Technology Research

Unlike other types of engineering construction, road engineering after theearthquake also shoulder the task of the transportation of relief personnel, material,equipment, thus during the earthquake we should assure the smooth flow of lifelineroads. In the plateau region, especially with the the route altitude gradient changing ofzone region, due to the significant difference of regional tectonic setting、topographycharacteristics、geological lithology、climate and hydrological conditions of differentgradient zone highway engineering, the design principle、mechanism of earthquakedamage、damage analysis methods、principles and measures of prevention and control,emergency rescue principles and measures has obvious regional characteristics.This paper analyzed the characteristics of the natural environment of the plateaugradient with typical regional, and summarizes the plateau gradient zone highwaydesign differences from linear, pavement and subgrade.Combing with earthquakedamage instances, this article discussed failure patterns and characteristics especiallythree typical earthquake secondary geological disasters such as landslide、collapse anddebris flow, and made the main academic achievements as follow:1、Divided seismos-concurrent landslide into two types:slide shift limited landslidein wide sense and slide range perforation landslide in narrow sense, combing withearthquake damage instances, this paper analyzed affect mechanism and failurecharacteristics of that, summarized the control principle and engineering measures oflandslie in plateau gradient zone,and put forward plateau zone seismos landslidecontrol measures and sabotage region emergency rescue principle.2、 Summarized the collapse of the rock slope damage type and formationmechanism under earthquake, analyzed of the the rockfall impact factors and trajectory,generalized collapse control principles and measure in plateau gradient zone from theview of head off、kinetic energy decline、remove/firm and step aside, and put forwardplateau zone seismos collapse control measures and sabotage region emergency rescueprinciple.3、Summarized the type and influencing factors of debris flow in the conditions ofearthquake, mainly analyzed affect mechanism of seismos-rain flood debris flow in low altitude zone and seismos-glacier debris flow in high altitude zone considering of theplateau zone characteristics, discussed about plateau zone seismos debris flow controlmeasures from the view of different valley characteristics, and proposed relatedemergency rescue measures.
