某工程大型地下厂房围岩损伤特征分析

STUDY ON DAMAGE MECHANICAL CHARACTER OF ROCKMASS SURROUNDING A HUGE UNDERGROUND POWERHOUSE

依据现场工程岩体节理的统计分析 ,应用损伤力学的研究方法 ,计算地下厂房各个岩体结构分区的损伤张量 ,建立应用最大主损伤值评价工程岩体质量的分析模型并应用于实践。

According to the result of joint statistics, the damage tensor of each rockmass structure zone is calculated by the method of damage mechanics. The model evaluating the quality of engineering rockmass with the maximal principal damage value is set up and used in engineering practice.
