Based on the damage plasticity theory of concrete , a realistic nonlinear model of highway tunnel struc -ture was established.The calculations and analysis were carried out by ABAQUS which is large finite element software . The calculation results revealed the mechanism of cracking in lining structure of the highway tunnel .Furthermore, the distribution characteristics and laws of damage value , and stress of the lining structure under collapse rock and sur -rounding rock bias were obtained .
