Abstract: The volume of soil and rock is a major part in Transportation engineering, the reasonable dispenses of digging and filling could lower cost and promote income, the economical transportation distance is also a major part in dispenses of soil and rock. For this article, considering shortage of land resource, deduces a modified formula about economical transportation distance, and apply for dispenses of Han-Xiao High way, so a good conclusion is available

Key words: cost of engineering, dispenses of soil and rock, Economical transportation distance, modified formula, adaptability comparison

摘要： 土石方在交通土建工程中占很大的比例，而挖、填方比例的合理调配可以降低造价，提高效益，经济运距 则是进行土石方调配的关键。本文结合土地资源紧张的现实，推导出了经济运距的修正公式，并应用于汉孝高速 公路土石方调配，得到了比较好的结果。
