Experiment Study on Concrete Block Model Shaft Lining Used in Freezing Shaft

The deformation characteristic load-deformation curve, failure Patten and the load bearing capacity of concrete block shaft lining under uniform and non-uniform load condition are presented. They were got from the mechanical property test of layered concrete block masses. And the large Structure test of concrete block lining series of test data are provided for the design and calculation of concrete block lining, and the deformation control under sinking of freezing shaft in which this kind of lining is utilized.
