Study on the Seasonal Stability Evolution Law of Expansive Soft Rock Roadway

In rock engineering such as mine engineering and tunnel engineering, the rock mass structure plays a key role in the strength, seepage and stability of the rock mass. Therefore, the geometric parameter statistics of structural planes in rock mass engineering is an important geological survey work. Traditional rock mass structural plane measurement methods are limited by various on-site conditions. With the application of advanced measurement technologies in underground mines, the measurement methods of rock mass structural planes have also been updated. Among them, photogrammetry and 3D laser scanning measurement are new methods suitable for measuring the structural planes of underground rock mass. Through the detailed comparison and analysis of three typical structural plane measurement methods, the 3D laser scanning technology has proven to have an incomparable advantage in the collection of rock mass structure measurement. It has explored a new way for the rapid collection of rock mass structure plane occurrence in areas with harsh geological conditions.在矿山工程、隧道工程等岩石工程领域，岩体结构对岩体的强度、渗流特性与稳定性起着关键性作用。因此，岩体工程中结构面的几何参数统计是一项重要的地质勘察工作。传统岩体结构面测量方法受各类现场条件制约。随着先进测量技术在地下矿山中的应用，岩体结构面测量方法也得到了更新迭代。其中，摄影测量（Photogrammetry）与三维激光扫描测量（3D laser scanning measurement）是适用于地下岩体结构面测量的新型方法。通过对三种典型结构面测量方法的详细对比分析，已证实三维激光扫描技术在岩体结构测量数据采集方面具备无可比拟的优势，为地质条件恶劣区域的岩体结构面产状快速采集探索了全新路径。
