Abstract
According to the actual situation of large range road disasters in seasonal frozen area, the road safety can reflect by the slope stability, the subgrade stability, the bridge safety and the ice(snow) on the road.The objective of this paper is to present a new monitoring and early-warning system, which can be used on the large range road in seasonal frozen area. The system consists of four parts, which are slope monitoring system, subgrade monitoring system, bridge monitoring system and ice(snow) monitoring system. In this system, the small world theory is used to build an IPv6 p2p network structure and semi-structured data is used to store any type of early-warning data. In addition, a bridge in western Changchun City in Jilin Province was selected as the case study example. Monitoring and early-warning results show that the system is stable and efficient , also can improve the scalability and reduce the dependence on central server in IPv6 network.
