In order to solve the problem of shield equipment
selection in complex geology and surrounding environment, the paper defines and
classifies multimode shield according to its development and research status. It is
mainly divided into several types, such as earth pressure/mud water dualmode shield, earth pressure/TBM dualmode
shield, mud water/TBM dualmode shield. And then
combined with the first phase project of Nanning rail transit line 5, the main
working principle, characteristics, applicable scope and adaptive design of
earth pressure/slurry balance dualmode shield machine
are analyzed. The results show that : The earth pressure/mud water balance
shield has wide geological adaptability, high equipment utilization ratio and
low construction cost, which solves the problem of shield equipment selection
under different geological conditions in the same section. To a certain extent,
it provides a set of reliable solution for the geological complex and
engineering sensitive zone.
