Investigating mineral alteration and infilling of discontinuities in naturally deformed rocks as a guide to rock mass rheology

自然变形岩石的结构分析将用于研究自然形成的不连续表面的起源，物理特性和摩擦行为。 自然变形岩体中的不连续性通常会发生变化，并填充有复杂的矿物质组合，并且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。 通过结合结构地质技术和实验室实验，并参考现有的数据，现场规模的岩体变形来自工程岩石力学调查，预测岩体流变的基础地质观测的方法将设计和测试。

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.
