The excavation construction of large underground cavern chambers is prone to induce the relaxation of the surrounding rock unloading. Generally, in-situ testing methods are used to determine the relaxation depth during the construction period, but there is a lack of effective means to estimate the relaxation depth during the survey and design stage. Firstly, the characteristics of surrounding rock unloading relaxation in cavern groups are analyzed, and it is pointed out that the adjustment of the stress field is the direct cause driving the macro-mesoscopic evolution of surrounding rock and the decline of bearing capacity. At present, borehole acoustic testing technology and acoustic change rate indicators are mostly used to identify the surrounding rock relaxation depth. The surrounding rock relaxation depth of underground powerhouse for the built hydropower station is generally within 5 m. Then, a quantitative analysis method for rock mass excavation unloading relaxation is established considering damage and deterioration effects, and quantitative indicators and criteria for the evolution of surrounding rock unloading relaxation are proposed. Finally, the assessment of surrounding rock unloading relaxation is carried out for actual projects. It is found that the proposed method and criteria can further quantitatively analyze the degree of surrounding rock disturbed by excavation on the basis of traditional plastic zone indicators, so as to realize more accurate and targeted cavern support design.

大型地下洞室开挖施工易诱发围岩卸荷松弛,一般在施工期采用现场测试手段查明其松弛深度,但在勘察设计阶段尚缺乏有效手段估计松弛深度。首先分析了洞室群的围岩卸荷松弛特征,指出应力场调整是驱动围岩宏细观演化和承载力下降的直接原因,目前多采用钻孔声波测试技术和声波变化率指标来查明围岩松弛深度,且已建水电站地下厂房的围岩松弛深度一般在5 m以内;然后,建立了考虑损伤劣化效应的岩体开挖卸荷松弛量化分析方法,并提出围岩卸荷松弛演化的量化指标和定量判据;最后,针对实际工程开展了围岩卸荷松弛评估,发现所提方法和判据能够在传统塑性区指标基础上进一步量化分析围岩受到开挖扰动的程度,实现更精准和更具针对性的洞室支护设计。

大型地下洞室开挖施工易诱发围岩卸荷松弛,一般在施工期采用现场测试手段查明其松弛深度,但在勘察设计阶段尚缺乏有效手段估计松弛深度。首先分析了洞室群的围岩卸荷松弛特征,指出应力场调整是驱动围岩宏细观演化和承载力下降的直接原因,目前多采用钻孔声波测试技术和声波变化率指标来查明围岩松弛深度,且已建水电站地下厂房的围岩松弛深度一般在5 m以内;然后,建立了考虑损伤劣化效应的岩体开挖卸荷松弛量化分析方法,并提出围岩卸荷松弛演化的量化指标和定量判据;最后,针对实际工程开展了围岩卸荷松弛评估,发现所提方法和判据能够在传统塑性区指标基础上进一步量化分析围岩受到开挖扰动的程度,实现更精准和更具针对性的洞室支护设计。

The excavation construction of large underground cavern chambers is prone to induce the relaxation of the surrounding rock unloading. Generally, in-situ testing methods are used to determine the relaxation depth during the construction period, but there is a lack of effective means to estimate the relaxation depth during the survey and design stage. Firstly, the characteristics of surrounding rock unloading relaxation in cavern groups are analyzed, and it is pointed out that the adjustment of the stress field is the direct cause driving the macro-mesoscopic evolution of surrounding rock and the decline of bearing capacity. At present, borehole acoustic testing technology and acoustic change rate indicators are mostly used to identify the surrounding rock relaxation depth. The surrounding rock relaxation depth of underground powerhouse for the built hydropower station is generally within 5 m. Then, a quantitative analysis method for rock mass excavation unloading relaxation is established considering damage and deterioration effects, and quantitative indicators and criteria for the evolution of surrounding rock unloading relaxation are proposed. Finally, the assessment of surrounding rock unloading relaxation is carried out for actual projects. It is found that the proposed method and criteria can further quantitatively analyze the degree of surrounding rock disturbed by excavation on the basis of traditional plastic zone indicators, so as to realize more accurate and targeted cavern support design.
