In view of the problem of concrete crack of rock anchor beam in the period of construction,the paper introduces the main loads which could produce adverse stress.According to the measured value of inhomogeneous displacement of rock face,the elastic finite element analysis is been done by ANSYS,and the results show that the larger tensile stresses which are caused by inhomogeneous displacement of rock face are located in the concrete near free face.The simulation of temperature field and stress field has been done,and the analysis of occurrence and development of temperature and stress in middle section shows that main reason of concrete crack is the temperature distribution and its ongoing change.
