摘要
为保证岩土勘察工作的合理开展,提出了岩土勘察工作中工程地质条件及地层特性研究。通过研究岩土勘察工作中工程地质条件,水文地质条件包括:矿床含水岩组水文地质特征、地下水补给和迳流条件以及地下水动态变化规律;自然地理条件包括:总体地势情况、气候类型、海拔、相对高差以及地形地貌特征;岩土物理性质条件包括:直接测得的岩土物理性质条件以及间接换算测得的岩土物理性质条件。通过研究岩土勘察工作中地层特性,掌握工作区重力及航磁异常特征、岩浆岩特征以及变质作用及热液蚀变。
In order to ensure the reasonable development of geotechnical investigation,the engineering geological conditions and stratum characteristics in geotechnical investigation are proposed.Through the study of engineering geological conditions in geotechnical investigation,hydrogeological conditions include:hydrogeological characteristics of water bearing rock formation of the deposit,groundwater recharge and runoff conditions,and groundwater dynamic change law;natural geographical conditions include:overall terrain,climate type,altitude,relative height difference and landform characteristics;geotechnical physical properties include:directly measured rock Soil physical property conditions and indirect conversion measured geotechnical physical property conditions.Through the study of strata characteristics in geotechnical investigation,the characteristics of gravity and aeromagnetic anomalies,magmatic rocks,metamorphism and hydrothermal alteration are mastered.
