The disaster of large deformation has become a major issue to solve urgently in the field of transportation, water conservancy and deep resources development in China. From the example of Datong River into Huangshui River TBM extrusion segment dislocation caused by the large deformation, repair and control method of large deformation dislocation was suggested from back analysis of field measurement. The results had guiding significance for other expansive mudstone jamming accident and engineering segment dislocation of the turnaround.
