摘要
地下厂房岩壁吊车梁稳定性分析有多种方法,如刚体极限平衡法、力失平衡法、弹性地基梁法、有限元法、DDA法等,在这些方法中,因刚体极限平衡法的方便性,而被广泛应用;然而目前在应用刚体极限平衡法分析岩壁吊车梁稳定性的理论和思路上,还存在一点值得商榷的地方,以工程实例对这一点进行了详细的剖析。
Many methods are used to analyze the stability of rock - wall crane beam in underground powerhouse such as rigid body limit equilibrium method, force-lost balancing method, elastic foundation beam method, finite element method and DDA method, among which, the rigid body limit equilibrium method is widely used because of its convenience. However, some theory and concept of rigid body equilibrium method used to analyze rock - wall crane beam stability still remain to be discussed. For this, some project case histories are illustrated.
