Abstract：
The launching opening is a concrete enclosure structure which uses fiber glass bar to replace ordinary steel bar, so it is free of artificial chiseling and could realize barrier-free shield launching construction. Based on practical calculation, mechanical construction behaviors were analyzed on the aspects of pile back soil, enclosure pile and land settlement during construction of barrier-free launching. Numerical simulative land settlement was compared with measurement result of shield barrier-free launching segment and it was proved that the whole construction process is relatively safe and stable and is worth of comprehensive promotion.
