Analysis of Telecommunication Conduit Damages in the Great East Japan Earthquake, and Effective Lining Repair Technology
Abstract eng: Focusing on uneven settlement of ground near a box culvert, seen at the time of the Great East Japan Earthquake, this study is based on an example in which optical cables actually break as a result of that settlement. It was confirmed that the shear force acting on optical cables after the joints of existing telecommunication conduit were broken by seismic motion was reduced by applying a new technology for restoring cable-containing conduit. A formula for calculating shear force acting on an optical cable is presented, and shear-load bearing capacity based on an earthquake-resistant design incorporating the new technology is demonstrated. It is anticipated that the reliability of communication networks will be improved by applying this technology at sections in which conduit traverses box culverts.
