摘要
对复杂围岩提出了能量耗散本构模型 ,提出了考虑单元损伤、塑性和受拉破坏情况下的能量耗散公式。对洞群开挖支护提出了岩体施工过程力学 ,能量转化和时间空间载荷变化分析等 3个原理。结合溪洛渡水电工程洞群稳定问题做了 4个方案的施工顺序优化比较分析 。
The energy dissipation constitutive model for complex surrounding rock has been estabilished.The element damage,plasticity and tension fracture are considered in the formula of energy dissipation.Three principles of construction process mechanics,energy transformation and analysis of loading change in time and space for excavation and supporting of rock caverns have been presented.An application computation for comparing four schemes of construction order optimazation related to the rock cavern stability of Xiluodu hydraulic power project have made as well.The optimized construction scheme was obtained.
