摘要
贵州省岩溶区公路建设过程中出现了众多的土岩混合边坡,通过对贵州省西部典型的二叠系-三叠系碳酸盐岩地层区域的公路土岩混合边坡的地层特征岩溶发育的综合分析,根据坡体岩土体结构与岩溶发育情况,将土岩混合边坡分为3种典型类型,逐一分析其潜在的变形破坏机制,揭示典型致灾模式,基于技术可行性、经济合理性提出全过程灾变调控措施。
During the highway construction in the karst area of Guizhou province,a large number of mixed rock-soil slopes have emerged.Based on the comprehensive analysis of the karst development of the strata of the mixed rock-soil mixed rock slopes in the typical Permian-Triassic carbonate strata area in western Guizhou Province,the rock-soil mixed slope is divided into three typical types according to the rock-soil structure and karst development.The potential deformation and failure mechanism is analyzed one by one,and the typical disaster-causing mode is revealed.It is based on technical feasibility and economic rationality that the whole process of disaster control measure is proposed.
