Design of Rational Concatenation between Bridge and Portal for Mountain Tunnel on High and Steep Slope
Two typical structures to concatenate bridge and tunnel portal for railway line on high and steep mountainous slope have been presented according to the complicated landform and ground geology in a new high speed railway line. Comparison between the two types of bridge-tunnel concatenation shows that separated structure is more superior in lessening train vibration than integrated structure. The prevention of rockfall from front slope at tunnel portal is still considered in the two structures. The concatenation types presented in the paper can be used to guide the design of bridge-tunnel concatenation in high speed railway line on complex and abrupt mountainous slope.
