The methodology of visual simulation for tunnel engineering construction schedule is presented in this thesis.  Visualization of founding model,  calculation and result of construction schedule simulation are realized.  The simulate model of tunnel engineering construction schedule is founded.  Risk analysis and decision_making method of tunnel engineering construction schedule based on visual simulation are presented.  The resource optimization is conducted.  On the basis of studying the S curve theory and method of schedule management,  tunnel engineering construction schedule S curve real time management and control method based on visual simulation are presented. Practical engineering analysis is made.
