摘　　要：介绍了铁路桥梁是战争中袭击的重要目标之一,研究既有桥梁的战备保障预案对战时抢修和平时抢险都有重要意义。某高墩大跨桥梁是一座连续梁桥,技术含量高,达到20世纪90年代国内铁路桥梁领先水平,研究该桥的保障方案,具有一定的典型性。针对该桥结构特点,假设了5种破坏情况,设计了多种保障预案,重点研究了该桥的正桥保障方案,并对迂回线保障方案、倒运方案进行介绍。The railroad bridge is one of the important targets that will be assaulted in wartime. It is of great importance to study the guarantee project of existing bridges either for the sake of rush-repair during the war or emergency work during the peacetime. A certain high-rise-pier and large-span bridge is a continuous beam bridge built with advanced technology, which is of the leading level in domestic railroad bridges during the 90's of the 20th century. To study the guarantee project of the bridge has certain typical importance. Aiming at the characteristics of the structure of the bridge, we provide five supposed kinds of breakage cases, where the guarantee project of the main bridge is always the key of our study, and at the same time the guarantee projects of both the circuitous line and returning to conveyance are also suggested.
