| Abstract: | Since 1972,a great amount of protective constructions against debris flow have been built along Chensdu-Kunming Railway, which spended over 200 million yuan (RMB). These engineerings include chiefly drainage ditch,check dam,bypassing structure and resisted pile. Through paying a systematic return visit and investigation for these engineerings,it was found that most of them have made the investment yield well so as to promote the safety of railway operation.In this paper, the debris flow disasters and the protection constructions along ChengduKunming Railway have been outlined. In order to understand the working situation,the engineerings in 40 debris flow Sullies were surveyed and analysed emphatically in 1992. Among them,there are 5 debris flow gullies in which the aqueduts were built(taking the proportion of 13% in total), 32 debris flow gullies in which the drainage ditches were constructed (80% ), 17 debris flow gullies in which the check dams were erected (43% ) and 3 debris flow gullies in Which the resisted piles were constructed (8% ). Then,the efficiencies of these works, which were surveyed in the investigation,have been analysed and assessed in an all-round way,and the main technical factors for all kinds of works have been discussed in the meantime. Finally,several countermeasures to improve prevention engineering efficiencies are presented. |
