Construction method for shield tunnels passing underneath viaduct in multi-interval, small-clear-distance and overlapping manner
Disclosed is a construction method for shield tunnels passing underneath a viaduct in a multi-interval, small-clear-distance and overlapping manner. The construction method comprises the following steps: according to a principle of having the minimal deformation effect on pile foundations of a viaduct and the surrounding environment, formulating an optimal construction sequence for constructing shield tunnels passing underneath the viaduct in a multi-interval and overlapping manner; before a tunnel passes underneath the viaduct, carrying out active isolation reinforcement for construction in which a shield passes underneath for a short distance; constructing the shield tunnel passing underneath the viaduct; in an area where a plurality of shield tunnel sections pass underneath the viaduct in an overlapping manner, reinforcing a segment structure of the shield tunnel and reinforcing the interior of a tunnel hole; and carrying out track vibration reduction and isolation control in a section where the shield tunnel passes underneath the viaduct.
