Paper Title:
Mechanical Analysis of Tunnel Crossing Ground Fissure
  Abstract

Ground fissures is one of typical geo-hazards in Xi’an area, which may cause damage of various types of buildings, city lifeline projects and resources, especially endangering the construction and running of Xi’an Subway. Ground fissures in Xi’an were introduced firstly, and models of land deformations and section destroy were found around Xi’an subway. Secondly, based on the interface mechanics, mechanical characteristics of interface between stratum on fissure and metro tunnel are studied, and void underneath metro tunnel are analyzed emphatically. At last, the result of numerical simulation shows that distribution law and amount of frictional force, scale and location of void under the tunnel, influence deformation and stress of tunnel; and then it also provides a theory basis for effective forecast evolution process of void underneath.
