The four key factors influencing earthwork construction cost are summarized:machinery and equipment configuration and management, trans-portation distance and road condition, blasting cost control and scientific and reasonable construction organization. The corresponding control measures are put forward:rational allocation of machinery and equipment type and quantity, and effective management;earthwork balance allocation optimization, reasonable construction of temporary road;blasting scheme selection and timely blasting scheme adjustment;construction organization design optimiza-tion and construction interference factors treatment.%该文总结出四个影响施工土石方成本的关键因素，即机械设备配置及管理、运距及路况、石方爆破成本控制及科学合理组织施工。并针对关键影响因素提出相应控制措施：合理配置机械设备种类和数量，并进行有效管理；优化土方平衡调配方案、合理修建临时道路；优选爆破方案，并适时调整爆破方案；优化施工组织设计、妥善处理施工干扰因素。
