摘　　要：岩石作为地球表面的主要组成部分,可分为火成岩、沉积岩和变质岩,这种分类反映了岩石的成因和基本特性,对工程实践具有重要意义。岩石的矿物成分和结构决定了其物理和力学特性,直接影响工程的设计、施工和长期稳定性。常见岩石类型如花岗岩、玄武岩、砂岩、石灰岩、大理岩和片麻岩等在工程中具有广泛应用,这些岩石因其独特的形成过程和组成,表现出不同的强度、耐久性、透水性和加工性等特性,在建筑、道路、桥梁、隧道等工程领域发挥重要作用。As the main component of the earth’s surface, rocks can be divided into igneous rocks, sedimentary rocks and metamorphic rocks. This classification reflects the origin and basic characteristics of rocks, and is of great significance to engineering practice. The mineral composition and structure of a rock determine its physical and mechanical properties, which directly affect the design, construction and long-term stability of the project. Common rock types such as granite, basalt, sandstone, limestone, marble and gneiss are widely used in engineering. These rocks show different characteristics of strength, durability, permeability and workability due to their unique formation process and composition, and play an important role in construction, roads, Bridges, tunnels and other engineering fields.
