小型土木工程在山地灾害防治中的运用

Application of Small Scale Civil Engineering to Mountain Hazards Control

从防灾减灾的角度，分析了山洪、滑坡和泥石流等山地灾害的特点，简要介绍了西南山区山地灾害防治中常用的各类小型土木工程。给出了运用小型土木工程治理山地灾害的实例，并探讨了推广小型土木工程治理山地灾害需解决的问题。

Occurrence and damages of mountain hazards, such as torrent, landslides and debris flow, have close relation to human activities in mountain area. Most of mountain hazards widely dispersed over China are of small scale scattering over 31 provinical administrative districts. The experience in Alps and southwest mountains of China shows that small scale hazards were controlled successfully by small scale civil engineerings, with their advantages of simple construction, a little budget and great effectiveness in controlling hazards. For these engineerings, local materials and cheap labour are usually available. In addition, they can be combined with bio engineering easily. In 1995 1997, small scale civil engineerings were used to cotrol small landslides, debris flow gullies and torrent gullies successfully in the southwestern mountains. The problems concerned in the application to all mountains in China are related to the support of the government, a good design handbook, train for young engineers and combination between the hazards control and economy development in mountain area.
