摘要
通过地质勘察,查明隧址区地形地貌、地层岩性、构造、地震、地下水等工程地质条件,通过分析围岩力学性质、完整性、地下水、地应力等影响因素对围岩等级评级,为工程设计提供依据和建议,指导工程施工。
Through geological investigation, the engineering geological conditions such as topography and geomorphology, stratum lithology, structure, earthquake and groundwater are found out, and the grade rating of surrounding rock is analyzed by analyzing the mechanical properties, integrity, groundwater, ground stress and other influencing factors of surrounding rock. The purpose of this paper is to provide basis and suggestions for engineering design and guide the construction of the project.
