Abstract

Experiments on bending deformation of circumferential joint in shield tunneling segment for subway were conducted. Tangential load and bending moment were appl ied by two loading equipments. Tangential load was impressed firstly; when it wa s up to 750kN, it was kept at this level and bending moment was applied. The exp erimental curves of bending moment versus relative angle near the joint are obta ined, each of which was available for the surfaces of two segments contact both fully and partly.
