摘要
概述了岩体工程与岩体力学研究现状 ,讨论了现理论研究成果与岩体工程实际监测资料不相吻合的问题。分析其主要原因 ,是现岩体力学研究理论模型与岩体工程实际力学模型不相吻合所致。故应严格根据岩体工程实际力学动态相应进行岩体力学仿真分析 ,方可得到正确的分析成果。笔者曾提出“卸荷岩体力学”的概念 ,以归纳开挖卸荷岩体力学研究内容 ,已经高边坡和地下工程实例所验证 ,开挖卸荷岩体力学研究是岩体工程及其力学仿真分析的重要组成部分。
The recent research status of rock mass engineering and rock mass mechanics is briefly introduced in this paper,and the inconsisten cy of the current theoretical research result with the in-situ observation dat a and with the mechanical model of rock mass engineering is also discussed.It is stated in this paper that the right analysis result should be got from rock mas s mechanics simulating analysis and strictly according to the practical dynamic al situation in rock mass. Therefore the author has raised a new concept of 'un loading rock mass mechanics' to conclude the mechanical research content of exc avated rock mass which has been verified by practical project in high slope and underground engineering.The mechanics research on the excavation unloading rock mass is no doubt the significant section of rock mass engineering and its mechan ics simulation analysis.
