RISInfluence of Double-O-Tube Shield Rolling on Soil Deformation during Tunneling
Publisher: American Society of Civil Engineers
Abstract: One of the main disadvantages of the advanced tunneling technology of the double-O-tube (DOT) shield is unavoidable rolling of the shield machine during construction. In this study, the influence of the DOT shield rolling ...
Physical Model Tests and Discrete-Element Simulation of Pile and Soil Displacement Response Induced by DOT Shield Tunneling Based on Transparent Soil Technology
Publisher: ASCE
Abstract: With the advantages of saving underground space, small construction impact, and saving cost, the double-O-tube (DOT) shield tunneling construction technology has been used many times in the tunnel construction of particular ...
Experimental Investigation of Friction-Damped Self-Centering Prestressed Concrete Beam-Column Connections with Hidden Corbels
Publisher: ASCE
Abstract: This paper presents the experimental investigation of the hysteretic behavior of a self-centering prestressed concrete (SCPC) beam-to-column connection under cyclic loading. The SCPC connection utilizes unbonded posttensioned ...
