英语翻译
overbreak underbreak 超挖 欠挖
翻译：
Regarding to the calculating principle of tunnel excavation quantity,the calculating formula that if the standard horizontal cross section and the excavated cross section are compared,the excavation quantity of excavated cross section is calculated,if the difference of overbreak quantity and underbreak quantity is calculated from the above excavation quantity,the overbreak quantity and the underbreak quantity are calculated and the sum of overbreak quantity and underbreak quantity should be equal to the difference of the standard horizontal cross section and the excavated cross section was used.
And it was constructed to perform more efficient maintenance and management as showing such results on the excavating quantity as the graph like Figure26.
The overbreak quantity and the underbreak quantity at intervals of 1.0m determined like that are used to calculate total overbreak quantity and underbreak quantity at the up line and down line sections by total both cross section average method and are as per the Table 6.

有关隧道挖掘量的计算原理,计算公式（注：the calculating formula在这里好像和谁都不挨着,好像这里缺东西）,如果将标准水平断面与挖掘断面做比较,可以计算出挖掘断面的挖掘量；如果从上述挖掘量计算出超挖量与欠挖量的差,则可以计算出超挖量和欠挖量,而二者的和应该等于所使用的标准水平断面与挖掘断面之间的差.
它（指计算公式?）是以达到更加有效的维护和管理目的,实现如图26所示曲线所代表的挖掘量的计算结果而加以构建的.
以1.0米间隔确定的超挖量与欠挖量看似被两个断面的平均算法用来进行求和,并按照表6来计算出在上行线和下行线断面的总超挖量和总欠挖量.
注：你这三段之间相互不连贯,而且,句子中间似乎欠缺点什么东西,翻译起来难度较大.我大体翻译了一下,供参考吧!
