深部岩石工程力学特性及地应力测试研究综述

伴随中西部高山峡谷区水电及交通等工程的建设,与之相关的地下工程多呈现出超长、大埋深、高地应力、高外水压等特点,由此引发对深部岩石工程的岩石力学特性及地应力测试等科学问题的重视。简要综述了深部岩石试验技术、高应力复杂应力路径下的岩石力学特性、深部岩石的流变特征、深部围岩的质量分级与评价、地应力测试与分析等方面在过去10余年的进展,并对上述科学问题及后续研究重点进行了展望。

A Review of Researches on Mechanical Properties of Deep Rockmass Engineering and Geo-stress Measurement

Hydropower and transportation underground projects in high mountain valley areas in central and western region of China have big length and depth, high geo-stress, and high external water pressure. Scientific problems regarding the mechanical properties of deep rock engineering and geo-stress measurement have drawn increasing attentions. The progresses of several key aspects over the past decade are reviewed, including test technique of deep rock, mechanical properties of rocks under high stress condition and complex stress path, rheological characteristics of deep rock, quality evaluation and classification of deep surrounding rock mass, and geo-stress measurement technique in deep rockmass. Future research prospects of the mentioned scientific problems are also highlighted.
