地下厂房洞室群岩体蠕变特性分析

Study on the Creep Property of Underground Powerhouse Cavities

岩体蠕变是大型地下工程围岩稳定性分析中的一项重要研究内容,它为地下洞室群的长期稳定性研究提供理论依据.本文通过对某地下厂房洞室群近期监测资料的分析,研究了其地下洞室群的蠕变特性,一方面丰富了蠕变分析的理论和方法,另一方面可以对该地下厂房洞室群在运行期的长期稳定性进行预测.

Rock creep is very important research content of the surrounding rock stability analysis in a large underground engineering.It provides theoretical foundation for long-term stability and reliability study of the underground cavities.This paper analyzes the recent monitoring data and studies the underground cavities creep properties,enriches creep analysis theory and method,and also analyses and forecast underground workshop cavities stability of operation period.
