| 摘 要： | 介绍了介西线孝义市区改线铁路工程概况，针对跨越西许河的西许河大桥进行防洪评价。由于西许河大桥下游384m处孝石线公路的排洪涵洞已基本堵死，截断了西许河的泄洪通道，本次设计将公路上游视作水库进行计算。计算结果表明，大桥防洪标准不达100年一遇设计标准，提出两种防洪补救措施。

| Abstract: | Based on engineering situation of Jiexi railway in Xiaoyi city, evaluation on flood control of Xixu bridge crossing Xixu River is especially done. There is highway bridge named Xiaoshi highway at the downstream of Xixu bridge with the distance of 384 meters. Because flood draining culverts of Xiaoshi highway are plugged, the flood discharge channel of Xixu River is cut off. This paper considers the region at the upstream of Xiaoshi highway as reservoir. The results show that flood control standard of Xixu bridge doesn＇t meet design standard of 100 years. At last. two remedy ootions are out forward. |
