Review and Prospect of Earthquake Resistance and Disaster Mitigation Technology of Highway Engineering
Haitao Zhou · Journal of Highway and Transportation Research and Development · 2010
In order to fully master the opportunities and challenges of earthquake resistance and disaster mitigation technology of highway engineering,the development of highway engineering's seismic technology was reviewed,four main features,including the theory developed from static method to dynamic method,fortification concepts developed from simply seismic resistance to mitigation and isolation method,seismic design method developed from strength criteria to performance-based design method,and fortification object developed from one single highway structures to highway network and from earthquake disaster resistance to multi-disaster resistance,were summarized.Based on the conditions in Wenchuan and Yushu earthquake,three current deficiencies of highway system,including weaker road network anti-seismic capacity,acquisition difficulty of earthquake disaster information of highway,and secondary disasters caused serious loss,were put forward.The view that highway structures behaved well as a whole was put forward.Finally,five research areas that should be enhanced,including anti-seismic capacity of road network,road hazards monitoring and assessment using remote sensing technology,prevention technology of secondary disasters after earthquake,development of new technology and evaluation of existing techniques,emergency inspect and evaluation and emergency traffic-keeping techniques of highway structures,were suggested.
