摘　　要：挡土墙是指支承路基填土或山坡土体、防止填土或土体变形失稳的构造物。在挡土墙横断面中,与被支承土体直接接触的部位称为墙背;与墙背相对的、临空的部位称为墙面;与地基直接接触的部位称为基地;与基底相对的、墙的顶面称为墙顶;基底的前端称为墙趾;基底的后端称为墙踵。文章从挡土墙的概念、种类、划分与应用出发,探讨了挡土墙布置原则、挡土墙设计和基础设计,从而为解决长输管道水工保护问题提供思路。The bulkhead is refers to the supporting roadbed earth fill either the hillside soil body,prevents the earth fill or the soil body distortion jitter structure.In the bulkhead cross section,with is called by the supporting soil body immediate contact＇s spot the wall back;With the wall back relative,is called the wall surface near the spatial spot;Is called the base with the ground immediate contact＇s spot;With the basis relative,the wall top is called the wall to go against;Basis front end is called the wall foot;Basis rear end is called the wall heel.From the bulkhead concept,the type,the division and the application embarked,have discussed the bulkhead arrangement principle,the bulkhead design and the foundation design,thus to solve long loses the pipeline water conservancy project to protect provides the mentality.
