000018496 520__ $$2eng$$aCommunications conduits contribute to more-efficient operation and maintenance of underground cables, and must provide protection for the cables within the conduits when earthquakes occur. For protection from unexpected large-scale disasters, Nippon Telegraph and Telephone Corporation (hereafter, NTT) has been tackling various measures based on the basic antidisaster policies to enhance communication network reliability. In this study, a new logic tool for evaluating the seismic of underground communications conduits and implementing seismic countermeasure of lining pipes on a vast quantity of underground conduits efficiently and effectively. This new logic evaluates the weakness points of pipeline by analyzing conduits information (available from various in-house shared database), the ground type (detailed geological data about Japan), and earthquake parameter (PGV, PGA, Vs, etc.), as well as the probability of damage estimated from damage data (such as that for the 2011 Tohoku Earthquake). This paper will show the seismic assessment flow and a case study to prove the applicability of this method. More effective countermeasures must be taken by performing comprehensive evaluations that combine the above information while taking into account reliability, economy, feasibility, environmental conservation, and other factors in the future.
