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

对自然变形岩石的结构分析将被用来研究自然形成的不连续面的成因、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质组合改变和充填，在工程开挖中是控制岩体流变性(包括强度和稳定性)的主要因素。通过将构造地质技术与室内实验相结合，并参考工程岩石力学研究中已有的现场范围的岩体变形数据，设计并验证了一种根据基础地质观测预测岩体流变性的方法。

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.
