摘要: 天然洞体不稳定是绝对的,稳定是相对的。天然洞体围岩的顶板、底板、侧面三者的稳定,顶板的稳定最重要。顶板的稳定性,与天然洞体的形成原因,岩面的成层条件、断面形状、裂隙情况,漏水情况,天然洞体形成和稳定的时间,山体的地质构造条件等有关。Abstract: The Instability of natural cave is absolute and its stability is relative. Among the top, base and lateral wall of natural cave, the stability of top is most important, which dependent on some factors, sach as the formation mechanism, the stratfied condition, the section figure, the conditon of fissure and water seepage, the time of formation and stabilization, the geological formation and etc.
