Abstract: Debris flow is main disaster along highway in mountainius region．On the basis of research results to debris flow along highway for years，authors of this paper draw up《Construction Guidbook of Civil Engineering against Debris Flow along Highway》which is matched with 《Design Guidbook of Civil Engineering against Debris Flow along Higllways》．The construction guidbook include nine parts，i．e．general rules，prepamsion before cortstructlon，and construction of high-speed drainage structure，sab-mergecl tunnel，rock screen，protect bank strueture，diversion dam，wing-shaped converge structure，aqueduct and bed-roughened piles． In the paper,items about construction of general rules，preparaslon before construction，and eonstructlon both high-speed drainage strueture and sub-merged tunnel, which can give some important lessonsin construction of strueture to control debris flow along highway，further provide important foundation to revise bearing technique codes about constructing and maintaining of highways．

Key words: debris flow along highway, control structure, construction guidbook, general rules, construction of high-speed drainage structure, eonstructlon of sub-merged tunnel

摘要： 作者根据多年来对公路泥石流的研究成果积累，编制了与所编制的《公路泥石流防治工程设计指南》相匹配的《公路泥石流防治工程施工指南》(以下简称《施工指南》)．《施工指南》包括九部分，即总则和施工前的准备，以及速流结构、底埋隧道、拦渣坝、护岸结构、导流堤、翼型墩汇流结构、渡槽及糙底群桩等核心技术的施工．本文介绍了总则、施工前的准备、速流结构及底埋隧道的施工技术条文，为公路泥石流防治工程施工提供了重要技术借鉴。也为公路建设及养护相关技术规范的修改提供了重要依据．
