Construction Optimization of the Bridge-Tunnel Sections
The construction method of the joint section connecting bridge and tunnel was simulated by FEM.After Calculating and comparing the result of stresses and effect of displacement-control in the surrounding rock under three methods of construction,it shown that the side heading method was very advantageous for the stress concentration,and the CRD method provided a good control of bottom heave,as for the top heave,the double side heading method was more favorable.From the dynamic analysis,the vehicle load is found to have,though small,wide influence.Whats more,the lapping distance between the bridge and tunnel is better more than 4m,and the influence from the high running speed should be paid attention to.
