根据深圳大型土石方工程的内容介绍了土石方工程的设备配套计算方法。主要论述了钻孔设备、挖装机械、运输设备的配套原则和计算方法，并结合现行公路和市政预算定额，对配套方案的生产能力进行了对比分析。优化工程设备配套是以机械化施工为主的工程项目提高生产效率和节约工程成本的关键。

Taking a largescale earth/rock engineering works in Shenzhen as an example, the paper presents the calculation method for the equipment matching of an earth/rock engineering works. The paper places its emphasis on the expatiation of the matching principle and calculation method for the drilling equipment, excavating and loading equipment and transportation equipment. Furthermore, the paper makes comparisons between the production capability of theadopted matchingscheme and the quota data specified in the highway budget and municipal budget. The optimization of the equipment matching is of fundamental importance for the project to improve its production efficiency and reduce its engineering cost.
