摘　　要：镇墩是供水管道工程中常见而又非常重要的构筑物，对管道的安全运行有非常重要的作用。对常见的镇墩类型进行归纳，提出四种典型镇墩形式，并对其进行受力分析及稳定计算。以南水北调中线配套工程为例，给出四种典型镇墩结构形体，并以管线中最常用的水平弯管镇墩进行求解计算，采用相关参数，满足稳定计算，最终给出合理尺寸。对供水工程中镇墩选型及理论分析有重要的参考意义。Anchor blocks are common and very important structures in water supply pipeline engineering and are a very important role to the safe operation of pipelines, the article summarized the common type of anchor blocks, put forward four kinds of typical anchor blocks, and carries on the stress analysis and stability calculation. Taking Middle Route of South-to-North Water Transfer Project for example,presented four typical anchor blocks, and solved calculation to the most common horizontal bend anchor blocks, using the relevant parameters to meet stability calcula- tion, and ultimately given a reasonable size. This paper has important reference meaning to the selection of anchor blocks and theoretical analysis in water supply engineering.
