Abstract: Based on the modification of Sun’s solution, additional load formulas caused by bulkhead additive thrust and force of friction between shield and soil in double-o-tube (DOT) shield tunneling are put forward by elastic Mindlin solution. Assumed soil is Winkler model, additional load in vertical direction caused by soil loss is deduced by using random medium theory. A calculation formula additional load caused by DOT shield tunnel construction vertical crossed adjacent underground pipeline is deduced. The results show that: during the pass of DOT shield machine, additional load caused by the friction force between shield and soil plays a leading role; additional load on adjacent underground pipeline induced by bulkhead additive thrust is very small which can be negligible; additional load in z direction is mainly caused by soil loss, and the maximum value generally appears above the axis; when pipeline buried depth is near tunnel, the maximum additional load in z direction appears near to center of each single round.

Key words: double-o-tube shield tunneling, underground pipelines, additional load, soil loss
