Abstract

Recently artificial ground freezing has become more frequently used for construction of underground facilities in urban areas because it makes underground excavation possible without lowering the groundwater level. To use artificial ground freezing in a underground excavation project, the adfreeze shear strength at the joint between an underground structure and frozen soil should be large enough to ensure structural stability. For that reason, the authors have previously proposed a method for enhancement of adfreeze shear strength by the use of stud connectors. This paper addresses a series of small-scale laboratory tests and large-scale verifying experiments that help formulate reinforcing effects of the proposed stud connectors on the adfreeze shear strength.
