摘要
为了方便地评价安全效益，将铁路泄洪防洪工程分为泄洪工程和防治工程两部分。单项工程的评价采用定性调查判断为主，定量计算结果为辅的方法给出安全效益等级。同时，对拦砂坝群和防治工程的安全效益评价方法进行了探讨，在此基础上，给出了泄洪防洪工程的总体安全效益评价。结论可供铁路工务部门参考使用。
In order to conveniently evaluate the safety benefit, the railway's protection engineerings are divided into flood-relief projects and flood-control projects in this paper. The evaluation of safety benefit for any single project depends upon qua1itative analysis as the dominant factor and quantitative computation. Then, the methods of estimating damgroup and flood-control projects are discussed. Finally an evaluation table for the overall safety benefit of railway's protection engineering projeets is given.
