Analysis and treatment of ground ruptures in xi'an

Abstract

With the development of society, economic and increment of population, urbanism is more and more obvious in the world. Especially in China, the trend is outstanding. However, different geological disasters impact the process heavily. Moreover, the type, form and incurring mechanism of urban disasters are complex in different cities. To avoid great loss in urban construction, it should be paid more attention 'to study them. As a heavy urban environment geological disaster, the ground rupture in Xi'an, Shaanxi Province, China, the tectonic model, relationships of earthquake and activities of ground ruptures are discussed in this article. Based on the distribution and mechanics of ground ruptures in Xi'an, the forming mechanics and treatments of ground ruptures are studied. At the same time, the relationship between activities of ground ruptures and earthquakes is also discussed. The analysis indicates: Excessive distilling ground water, surface water abundantly leakage and the oscillation affection of earthquake and large range tectonic can accelerate the velocity of activity of ruptures and cause abruptly activities. As a result, the disaster of ground rupture is obviously amplified.© 2008 Science Press Beijing and Springer-Verlag GmbH Berlin Heidelberg Geotechnical Engineering for Disaster Mitigation and Rehabilitation.
