摘要
古代地下工程闪烁着人类智慧的光芒。以徐州市楚王陵建立三维模型为例,采用大型通用数值分析软件ANSYS,研究古代地下工程的稳定性。在分析中考虑了地表地形、地面建筑和岩石风化等三因素对该工程稳定性的影响。分析表明,岩石风化作用明显影响古墓稳定性,地面建筑使得其原有变形加剧,地表地形的起伏在局部增加了岩石应力。三者对其薄弱部位影响较大,特别是在墓室入口的上下端角,应力集中较大,最容易发生围岩破坏。对古地下工程的保护和维护,应着重考虑到这些因素的影响。
Ancient underground engineering is an illustration of human intelligence. The Chuwang tomb in Xuzhou City is taken for example to set up a three-dimensional model. A large-scale general-purpose finite element analytical software ANSYS is adopted to study the stability of ancient underground work. Three factors are considered as terrain, surfac structure and rock decay and their influence on the stability of the tomb. Analysis shows that the rock decay affects the stability of tomb apparently, the surfac structure aggravates inherent deformation and terrain increases rock stress locally. These three factors have relatively large influence on the weak points, especially at the top and bottom comer of repository entry. At these points the surrounding rock damage can occur easily because the stress concentration is larger. When protecting and preserving towards ancient underground engineering, the influence of these factors should be taken into account.
