Research On Physical And Mechanical Properties Of Strata On Both Sides Of XI'an Ground Fractures

The subway project is different from general industrial and civilian Construction, must pass through these fractures in the zone, and not allowed to operate after completion of operations impact of security incidents. Therefore Based on the Xi'an-fracturess rock formation physical and mechanical properties for the project through the fractures in the structure provide the basis for the design, but also enriched the fractures of venues in Xi'an investigation and research projects of great theoretical and practical projects Significance.Firstly, the paper through the collect Xi'an ground fractures the relevant research materials, it describes geological environmental background of Xi'an ground fracture from the geological structure, landscape features, formation lithology, hydrological and geological conditions of varying terrain, Also describes the causes of Xi'an ground fractures in mechanisms and Xi'an fractures distribution and characteristics of activities.This paper describes the study focused on fractures in Xi'an with the physical and mechanical properties of rock and soil testing, the choice of activities in recent years compared keen f6, f9, f11 ,The drilling and the sampling work have been done on the typical section of Xi'an ground fractures. According to the earth laboratory test result, the analysis has been carried out on contrasting physical and mechanical properties of strata on both sides of Xi'an ground fractures. It is found that there is remarkable difference between the physical and mechanical properties on both sides of Xi'an ground fractures.
