Structural analysis of naturally deformed rock will be used to investigate the origin, physical characteristics and frictional behaviour of naturally formed discontinuity surfaces. Discontinuities in naturally deformed rock masses are typically altered and infilled with complex combinations of mineral matter and are a major control on the rheology, including strength and stability, of rock masses in engineering excavations. By combining structural geology techniques and laboratory experiments, and with reference to existing data on field-scale rock mass deformation derived from engineering rock mechanics investigations, a methodology for predicting rock mass rheology from fundamental geological observations will be devised and tested.

自然变形岩石的结构分析将用于研究自然形成的不连续面的起源、物理特征和摩擦行为。自然变形岩体中的不连续面通常被复杂的矿物组合改变和填充，是工程开挖中岩体流变学（包括强度和稳定性）的主要控制因素。通过将构造地质学技术与实验室实验相结合，并参考工程岩石力学研究中获得的现场尺度岩体变形的现有数据，设计和测试一种基于基础地质观测预测岩体流变的方法。
