亚碧罗水电站地下厂房施工开挖过程的FLAC数值模拟
Numerical simulation with FLAC on construction and excavation process of underground powerhouse of Yabiluo hydropower station
为了对怒江亚碧罗水电站地下厂房进行围岩稳定分析及对支护设计进行优化，采用差分软件FLAC模拟分析了地下厂房开挖支护过程。首先采用FLAC2D对地下洞室群布置格局进行比较、对喷锚支护设计进行优化并从中选出最佳方案，然后运用FLAC3D模拟最佳方案的施工开挖过程，研究洞室群围岩的开挖变形和应力状态。通过对地下洞室群开挖支护及未支护的模拟比较，分析了围岩在加固后的力学特性，及加固措施的作用。
his paper use FLAC2D to choose the best layout pattern of underground powerhouse of Yabiluo Hydropower Station in nujiang river. Different designs of rockbolt-shotcrete support for underground chamber are compared by FLAC2D.The construction and excavation process of underground powerhouse are simulated by FLAC3D. The pattern of deformation caused by excavation and stress state in surrounding rock mass are studied. The bolting supports are performed on the region of the underground powerhouse caverns; and the mechanical properties of the reinforced surrounding rock mass are analyzed.
