路基土石方是公路工程的一个主要工程量 ,在公路设计和线路方案比较中 ,路基土石方数量的多少是评价公路测设质量的主要技术经济指标之一。在编制公路施工组织计划和工程概预算时 ,更需准确地计算路基土石方数量 ,有关教科书对其计算方法已有详细的论述 ,在此不再赘述 ,本文仅 Subgrade earthwork is a major project of highway engineering. In the comparison of highway design and route plan, the number of earthwork in subgrade is one of the main technical and economic indexes to evaluate the quality of highway survey and set. In the preparation of highway construction planning and engineering estimates of the project, but also need to accurately calculate the amount of roadbed earthwork, textbooks on its calculation methods have been discussed in detail, not repeat them here, this article only
