Safety Problems of Engineering Structures at the Ground Fracture Sites Taking Xian’s for the Example
The ground fracture already becomes one of main city's geological disasters in China, this geological disaster is quite serious in Xi'an, of Shaanxi province capital city. In this city the ground fracture growth is intense, the causes of the fracture are very complex, the building and engineering structures to be able to have the serious destruction where the fracture passed through its base. In China national civil engineering design codes, the method which designs about buildings on the site of ground fracture is the blank, only Shaanxi Province engineering construction standard gives some specifications for site investigation and engineering design to the Xi'an ground, use the measure that is get out of the way to the building destruction, and rules the smallest required safety distance. Discovers the security problem of the engineering structures located in the ground fracture site is a complex topic, the Shaanxi Provincial engineering design standards have some deficiencies in the theory aspect. Reckon it is necessary to systematically research this topic. These work include more widely and deeply to investigate the ground fractures activity, found the ground uneven settlement modes in fracture belt, and analyzes safe reliability of all kind of building structure on the fracture site, as well as, analyses structures seismic capability.
