路基土石方调运中经济运距的研究

针对工程造价中土石方费用问题,介绍了路堤填方方案中经济运距常用的计算方法,以及考虑多种影响因素的综合计算方法;推导了最优经济运距分界点和平均经济运距分界点,并对两者进行了比较得出:前者比后者更加合理,总经济运距相对较小。最后针对多料点供应,提出了平均经济运距的计算方法。

Study on Economical Haul Distance in Subgrade Earthwork Allocation

For earthwork expense in engineering,the common calculation method for economical haul distance in embankment filling program and comprehensive calculation method considering multiple influencing factors are introduced.Thus the separation point of optimal economical haul distance and average economical haul distance are separately educed.Through comparison,it is indicated that the former is more reasonable than the latter for its total haul distance is relatively less.Finally,for multiple feeding points supply,the calculation method of average economical haul distance is put forward.
