针对5.12四川汶川地震过程中由于山崩在高山峡谷地带形成的滚石架空构造现象,引用崩积洞新概念加以概括和描述。根据多年工作经验和结合地震山崩情况,初步分析了地震山区崩积洞的成因、形成条件、工程特性等,并对包括房屋、公路工程、水利设施等工程建筑物的危害作了简略概述,提出了崩积洞为类似于岩溶洞穴的不良地质理念和具体处治措施,并用工程实例说明了处治措施的探讨性和有效性。强调在灾后重建中遇到崩积洞必须处治以确保建筑物安全的理念。
Aiming at the phenomenon of overhead rock formation formed by the landslide in alpine valley during the May 12 Wenchuan earthquake, the new concept of collapse cave is summarized and described. Based on years of work experience and landslide collapse, the causes, formation conditions and engineering features of the collapsed cave in the mountainous area are preliminary analyzed, and the hazards of engineering structures including houses, highway engineering and water conservancy facilities are briefly summarized. The collapse cave is similar to the karst caves of poor geological concepts and specific treatment measures, and engineering examples illustrate the feasibility and effectiveness of treatment measures. Emphasize the concept that in the post-disaster reconstruction, there is a cave that must be treated to ensure the safety of buildings.
