| 摘 要： | 介绍了利用岩溶地基溶洞顶板塑性区形成的潜在滑移通道作为岩溶顶板破坏的判别标准,通过对顶板厚度与溶洞跨度的关系、顶板厚度与承载力的关系及溶洞跨度与承载力的关系的研究表明,所提出的方法在实践中具有很好的可操作性,值得推广。

| Abstract: | The paper adopts the potential sliding passage formed by the plastic zones of the karst cave roof of the karst foundation as the judging standards for the damages of the karst roof,and proves by the relationship between the roof thickness and the karst span,the relationship between the roof thickness and the loading capacity,and the one between the karst span and the loading capacity that the methods have better operability,so it can be further expanded. |
