贵阳地区龙潭组地层勘察要点

Aummary of Information Construction Example in Deep Foundation Pit Engineering

随着贵阳城区的发展,以三叠系地层为主的中心两城区之外也开始大规模开展建设,大量接触了二叠系地层,二叠系尤以龙潭组最为复杂,本文以二叠系上统龙潭组地质情况为主要研究对象,从该地层的岩性、差异风化及岩溶发育等情况入手进行分析,根据贵阳龙潭组地层勘察工程实例总结该地层常见基础形式,并针对该地层特性,分析其地基承载力的挖掘空间,及贵阳地区龙潭组地层勘察过程中需要注意的问题。

Give priority to with Triassic strata along with the development of guiyang city, the center of the two outside cities also began to large-scale construction, a lot of contact with the Permian strata, especially in Permian longtan group of the most complex, based on the geology series on the Permian longtan group as the main research object, from the formation lithology, differential weathering, and through the analysis of the karst development, and so on and so forth, according to guiyang longtan stratum survey and engineering examples, summarizes the common foundation forms, formation and aiming at the formation characteristics, analysis of the foundation bearing capacity of the mining space, the final summary of guiyang region of longtan formation need to be aware of the problems in the process of exploration.
