Abstract：By combining with the practical project of harnessing fractured shaft lining in thick alluvium，the mechanism of the stress-relief technique was investigated by physical simulation tests based on numerical simulation calculation and field measurement results. The process，position and form of the re-fracture of shaft lining and the characteristic of the stress-relief slot were analyzed. The mechanical mechanism of the stress-relief method to harness shaft lining fracture was obtained. The research provides theoretic foundation and engineering parameters for the harnessing of shaft lining fracture.
