采用偏心加载方法来量化约束效应并检查板在屈曲载荷下的能量平衡。结果表明，在一定的加载条件下，充填或破碎岩石材料提供的围压足以控制屈曲破坏。在偏心加载条件下，在地下开口附近的板中存储的应变能被确定为在1兆焦耳的量级。
An eccentric loading approach was applied to quantify confinement effects and examine the energy balance in a slab under buckling load. It was indicated that confining pressure provided by fill or broken rock material can prove adequate to control buckling failure under certain loading conditions. The stored strain energy in a slab under eccentric loading conditions, in the vicinity of underground openings was determined to be in the order of 1 MJ.
