The Construction And Disease Treatment Technology Of Asymmetrically Loaded Tunnel

Most of tunnel surrounding rocks are neither uniform granular materials nor homogeneous elastic continuum. Most of tunnel surrounding rocks are composed of some interbedded rock masses. And they have been cutting into different block rocks by joint and structural plane. After tunnel construction, it is both very complicated that secondary stress state and third stress state in the surrounding rock; the pressure of surrounding rock for tunnel structure is non-uniform.In this dissertation, destroy properties and variable influencing factors of tunnel under asymmetrically load are analyzed by load equation of overburden tunnel under asymmetrically load, secondary stress state of deep burden tunnel under asymmetrically load and comparison calculating. The construction and disease treatment technology of asymmetrically loaded tunnel are generalized by example of construction and asymmetrically loaded influencing factors.
