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.
