基于ubiquitous-joint model遍布节理模型,建立了溶洞-节理空间耦合模型。通过对施工期的变形反演,验证了模型的正确性和可靠性的同时,还进一步研究了施工后边坡的稳定性及失稳机制。结果表明:顺层节理和溶洞对边坡变形和稳定性有重大影响。两者的耦合作用加大施工期的变形的同时,也一定程度降低了边坡的安全性。研究成果对邻近溶洞的岩质边坡支护设计和研究具有重要的参考价值。
Abstract：Based on the ubiquitous-joint model, a spatial coupling model of karst caves and joints is established. Through deformation back-analysis during the construction period, the correctness and reliability of the model are verified, and further studies are conducted on the post-construction slope stability and failure mechanisms. The results show that bedding joints and karst caves have significant impacts on slope deformation and stability. Their coupling effects not only increase the deformation during construction, but also reduce the slope safety to a certain extent. The study results provide important reference value for the design and study of support systems for the rocky slopes adjacent to karst caves.
