复杂地貌条件下甘肃某公路土体工程性质评价
|
摘要
由于甘肃某公路沿线具有较复杂的地貌条件,在该公路工程地质勘察中,采用了工程地质钻探与室内土工试验等方法相结合的手段,对该公路沿线的地层岩性进行了调查,在此基础上,对公路沿线不同地貌单元下土体的物理力学性质进行了评价,得出了各土层的物理力学性质参数值,进而得出了公路沿线土体工程性质的评价结果,为该公路的设计与施工提出了有效的建议。
Due to the complicated geomorphic conditions of the highway of Gansu Province,several methods,such as engineering geological drilling and in-door soil tests have been used in the engineering geological investigation of the highway,the formation lithology of the highway has also been explored. In this way,the physical and mechanical properties of the soil mass in different geomorphic unit of the highway have been evaluated,the parameters of physical and mechanical properties of the soil layers have been got. Based on the evaluation results of the engineering properties of the soil mass,effective suggestions have been raised for the design and construction of the highway.
