摘　　要：破坝新建坝下埋管是海南对中小型病险水库坝下埋设涵管存在安全隐患的主要处理方案之一。破坝新建坝下埋管虽然技术简单,施工难度低,但是,如果设计和施工等环节稍不注意,容易出现问题,且处理难度高。本文重点介绍土坝坝下旧涵管挖除和埋设新涵管的设计要点,以及需要注意的细节和关键环节。Buried pipe under the broken dam new-built is one of main treatment plans aiming at safely hidden danger in buried pipes under the dam of Hainan middle and small risky reservoirs. Though buried pipe under the broken dam new- built have simple technology and easy construction, problems can be easily produced due to improper treatment in links such as design, construction, etc., and it is troublesome to solve these problems. Design keys of removing existing culvert pipes under the earth dam and burying new culvert pipes, precaution details and key links are mainly introduced in the paper.
