摘　　要：在铁路建设过程中,合理确定软土地基处理措施及其投资定额是铁路设计与施工者需要考虑的重要问题。本文以新建玉溪至磨憨铁路普洱车站强夯碎石墩处理软土地基施工为样本,在研究确定其施工参数、工艺流程及技术要求等问题的基础上,按照写实统计法和现场测定法,统计工料机消耗,分析测定强夯碎石墩定额,为弥补现行定额缺失和完善同类工程的概预算编制体系奠定基础。During the process of railway construction, it is an important issue for railway designers and constructors to reasonably determine soft soil foundation treatment measures and investment quota. In this paper, taking the construction of dynamic compaction gravel pier in Pu’er Station of Yuxi-Mohan Railway as a sample, on the basis of studying and determining the construction parameters, technological process, and technical requirements, statistics and field measurement are carried out to calculate the consumption of materials and machines, and analyze and determine the quota of dynamic compaction gravel pier, to make up the omissions in current quota and lay a foundation for perfecting the budget preparation system of similar projects.
