摘要/Abstract

摘要：

为揭示地下实验室施工开挖围岩损伤演化规律, 以甘肃北山埋深560 m的深部地下实验室为研究背景工程, 建立基于Hoek-Brown准则的深部围岩弹塑性损伤本构模型, 提出地下实验室施工开挖围岩损伤度的评价方法, 编制计算程序并对地下实验室施工开挖与超载过程进行数值模拟。研究结果表明: 洞室群施工开挖后围岩处于轻微弹性损伤状态, 并未出现塑性损伤, 洞室群整体安全稳定; 随着超载的增加, 围岩损伤区范围明显扩大, 当超载到2.5倍初始地应力时, 在洞室群交叉部位出现高度损伤区和开挖破裂区, 建议对洞群交叉部位加强支护, 并对中隔墙部位进行重点监控测量。研究成果为优化地下实验室建设方案提供理论指导。

关键词: 深部地下实验室, 弹塑性损伤本构模型, Hoek-Brown准则, 开挖损伤区, 开挖损伤度

Abstract:

In order to reveal the damage evolution law of the surrounding rock during the excavation of the underground research laboratory, the deep underground research laboratory with a buried depth of 560 m in Gansu Beishan was taken as the research background project. An elastic-plastic damage constitutive model of the deep surrounding rock based on the Hoek-Brown criterion was established. The evaluation method for the damage degree of surrounding rock during excavation was proposed. The calculation program was developed and numerical simulations of the excavation and overload processes of the underground research laboratory construction were conducted. The research results showed that after the excavation of the cavern group, the surrounding rock was in slight elastic damage state with no plastic damage, the cavern group was safe and stable as a whole; with the increase of overload, the damage areas of the surrounding rock expanded significantly; when the overload reached 2.5 times the initial in-situ stress, the high damage areas and excavation rupture areas appeared at the intersection of the cavern group. It was recommended to strengthen the support for the intersection of the cavern group and monitor the middle partition wall. The research results provided guidance for optimizing the construction scheme of the underground research laboratory.

Key words: deep underground laboratory, elastic-plastic damage constitutive model, Hoek-Brown criterion, excavation damage area, excavation damage degree
