Abstract:
This paper discusses the spatial distribution,activity characters of ground fissure and its destruction to municipal facilities, especially the interchange of Xi'an city. Based on the site investment data of Chang'an Road, Huzhu Road, Bypass in South Chang'an Road, the damage models of interchange by ground fissure is analyzed. The main models are horizontal tension and vertical dislocation. The authors propose reasonable measures to reduce the damage to interchange crossing the ground fissure, including taking special investigation on proposed project, structural measures and so on. Some instances of projects validate the efficiency of the measures. All these are foundation of further study of the technical countermeasures of disaster reduction engineering in the future.
