云南地区山间盆地软土发育种类多,工程特性复杂。通过收集云南省内交通工程软基勘察资料,归纳了云南山间盆地软土在区域构造、地形地貌、水文地质条件、软土分布等方面的特点,并对山间盆地软土的形成机理进行探讨,获得了云南地区软土在空间分布、物理力学性质的认识。分析了进行交通工程建设可能面临的工程地质问题,为云南山间盆地软土地基处理方案的选择提供参考。
There are many kinds of soft soil in the mountain basin in Yunnan Province and complicated engineering characteristics. By collecting the survey data of soft foundation of traffic engineering in Yunnan Province, the characteristics of soft soil in mountainous basin of Yunnan Province in terms of regional tectonics, topography, hydrogeological conditions and soft soil distribution are summarized. The forming mechanism of soft soil in mountainous basin is also discussed Explore, get the soft soil in Yunnan spatial distribution, physical and mechanical properties of understanding. This paper analyzes the engineering geological problems that may be faced during the construction of traffic engineering and provides references for the selection of soft soil foundation treatment schemes in Yunnan mountain basin.
