It is more difficult to construct stone subgrade than earthwork subgrade, so quality control should be strengthened in every link during construction. In the actual construction process, because the rock or geological structure is complex, blasting technology should be applied to achieve the purpose of earth and stone excavation. However, the application of blasting technology will bring many potential safety hazards, and even cause a large number of casualties in severe cases. Construction units should strengthen construction management, strictly regulate the application of technology, and avoid the occurrence of safety accidents. In order to ensure the high efficiency and safety of construction, the relevant engineering construction departments should fully display their guarantee function and reasonably apply the blasting technology. On the basis of introducing the engineering characteristics, this paper analyzes the construction requirements of earthwork and stone excavation of subgrade, and discusses how to correctly apply earthwork blasting technology in highway subgrade excavation engineering.
