摘要
深部重大工程灾害的孕育演化机制、预测预报和防治理论的研究是我国水利水电、交通、国防、深部基础物理实验等工程安全建设与运行以及金属矿山安全高效开采中的重大课题。本文介绍了973计划项目"深部重大工程灾害的孕育演化机制与动态调控理论"近5年的重要研究成果,包括:深部岩体结构与地应力特征、深部岩体变形破坏过程的分析方法、岩爆灾害的孕育演化机制、预测预警与调控技术、以及能量调控诱导破岩方法等方面,研究成果已成功应用于我国多个典型深部工程,推动了深部工程开挖开采过程中灾害的预测预报、防控理论和技术的进步。
Researches on evolution mechanism,forecast and protection theories of great disasters in deep engineering are of great importance in the safety construction and operation of hydraulics and hydroelectricity engineering,transportation engineering,national defense engineering and deep basic physical test engineering,and high efficiency exploitation of metal mine. The main research findings by the 973 project of "Theories on Evolution Mechanism and Dynamical Control of Great Disasters in Deep Engineering " are presented, including: rock structure and in-situ stress features in deep engineering,analytical methods of deformation and damage process of deep rock mass, evolution mechanism, forecast and control techniques of rockburst,rock exploitation method by energy control induction,etc. These results have been applied in several typical deep projects in our country,which have promoted the progress of forecast,protection theories and technology of disasters in the excavation and exploitation of deep engineering.
