Rock wall crane beam is a common bearing structure in underground powerhouse. Because it is directly supported on the surrounding rock, the stability of the rock crane beam is greatly affected by the geological conditions of the surrounding rock. Taking the rock wall crane beam of phase Ⅱ underground powerhouse of Fengning pumped storage power as an example, the distribution law of rock wall crane beam anchor stress and surrounding rock deformation were explained by analyzing the rock mass structural plane characteristics, the rock mass alteration effect as well as the in-situ observation data of the rock wall crane beam. Furthermore, the correlations between the bolt stress of the crane beam and the deformation of surrounding rock, the geological conditions as well as the construction process were deeply analyzed. The reasons for the large bolt stresses and the large deformations of surrounding rock of the crane beam were then explained, and the influence mechanism of rock mass structural plane and rock mass alteration on the stability of the crane beam was finally revealed. This research can provide technical support for the structural design, the construction organization and the safety demonstration of the rock wall crane beam, thus has practical engineering significance.

岩壁吊车梁是地下厂房中常见的承载构件,由于直接支承在围岩上,岩壁吊车梁的稳定性受围岩地质条件影响较大。以丰宁抽水蓄能电站二期地下厂房岩壁吊车梁为例,通过对地下厂房岩体结构面特征、岩体蚀变效应及岩壁吊车梁原位观测资料进行深入解析,阐释了岩壁吊车梁锚杆应力和围岩变形的分布规律,并深入分析了吊车梁锚杆应力同围岩变形、地质条件、施工进程等之间的关联,解译了岩壁吊车梁锚杆应力和围岩变形偏大的原因,最终揭示了岩体结构面和蚀变对岩壁吊车梁稳定性的影响机理。研究结果可为岩壁吊车梁结构设计、施工组织和安全论证提供技术支撑,具有实际工程意义。

岩壁吊车梁是地下厂房中常见的承载构件,由于直接支承在围岩上,岩壁吊车梁的稳定性受围岩地质条件影响较大。以丰宁抽水蓄能电站二期地下厂房岩壁吊车梁为例,通过对地下厂房岩体结构面特征、岩体蚀变效应及岩壁吊车梁原位观测资料进行深入解析,阐释了岩壁吊车梁锚杆应力和围岩变形的分布规律,并深入分析了吊车梁锚杆应力同围岩变形、地质条件、施工进程等之间的关联,解译了岩壁吊车梁锚杆应力和围岩变形偏大的原因,最终揭示了岩体结构面和蚀变对岩壁吊车梁稳定性的影响机理。研究结果可为岩壁吊车梁结构设计、施工组织和安全论证提供技术支撑,具有实际工程意义。

Rock wall crane beam is a common bearing structure in underground powerhouse. Because it is directly supported on the surrounding rock, the stability of the rock crane beam is greatly affected by the geological conditions of the surrounding rock. Taking the rock wall crane beam of phase Ⅱ underground powerhouse of Fengning pumped storage power as an example, the distribution law of rock wall crane beam anchor stress and surrounding rock deformation were explained by analyzing the rock mass structural plane characteristics, the rock mass alteration effect as well as the in-situ observation data of the rock wall crane beam. Furthermore, the correlations between the bolt stress of the crane beam and the deformation of surrounding rock, the geological conditions as well as the construction process were deeply analyzed. The reasons for the large bolt stresses and the large deformations of surrounding rock of the crane beam were then explained, and the influence mechanism of rock mass structural plane and rock mass alteration on the stability of the crane beam was finally revealed. This research can provide technical support for the structural design, the construction organization and the safety demonstration of the rock wall crane beam, thus has practical engineering significance.
