Abstract Research purposes: The type selection of shield machine is a key element for the shield construction and the shield adaptability is crucial to the construction cost，the construction schedule and the construction safety．Combined with the construction of river—crossing tunnel of Line 2 of Wuhan metro，this paper analyzes the adaptability of slurry shield tunnel and offers the the corresponding control measures．
Research conclusions:Based on the systematic engineering concept of the adaptability between man and the shield tunneling and the construction environment，the analysis is made for the basic concept and intension of the shield adaptability to the construction environment．According to the characteristics of the construction environment，such as The high hydraulic pressure，the shallow covering and the compound stratum etc，the control measures such as setting and adjusting appropriate face pressure，control of shield tunneling attitude，matching the grouting volume and speed with the shield speed are offered to reduce and control the construction risks，such as destabilization of excavation surface，mud pumping in the river bottom，block of the pumping mouth，mud leaking at the shield end and tunnel floating．This can provide the reference to the similar projects．
