| 摘 要： | 根据分段渠道地面线高于或低于设计堤顶线，高于或低于设计渠底线等不同情况，确定挖方段与填方段的长度，用棱柱体及斜三棱柱体体积公式计算填挖方量。以南水北调中线工程总干渠渠道为例，采用ＦＯＲ－ＴＲＡＮ－７７编制程序进行计算。计算结果表明，该方法比常用方法算出的挖方量，更接近实际值，由此产生的经济效益显著。

| Abstract: | The length of excavation section and filling section of the canal may be determined in accordance with various circumstances that the ground line of the canal in sections may be higher or lower than design levee crest line,and higher or lower than design canal base line. The volume of excavation and filling may be calculated by prismoidal formula and formula for truncated triangular prism. The authors take the canal of the master trunk canal of the median line of South-to-North Water Transfer Project for example. Calculation is carried out by programme FORTRAN - 77. Calculated results show this method is lass in excavation volume than the conventional ones. The calculated results are closer to actual values, thus bringing about significant economic benefits. |
