兰州黄河北岸高阶地挖山场地坡洪积层工程力学性质的研究

Study on Engineering Mechanical Properties of Slope Diluvium on Mountain Excavation Field of High Terraces on the North Bank of the Yellow River in Lanzhou

随着兰州北拓的不断推进,黄河高阶地与黄土梁峁复合区域的挖填方建设日益增多,场地地层条件愈加复杂。论文以兰州北高级阶地的大厚度挖方场地勘察为依托,对挖方揭露坡洪积层的工程力学性质进行多手段综合评价,提供承载力和变形指标,对地基基础方案给出建议,对类似工程场地的开发利用具有重要参考意义。

With the continuous advancement of north extension of Lanzhou,the excavation and filling construction in the composite area of the Yellow River high terrace and the Loess ridge is increasing,and the site stratigraphic conditions are becoming more and more complex.Based on the large thickness excavation site survey of Lanzhou North High terrace,this paper makes a multi-means comprehensive evaluation on the engineering mechanical properties of the slope diluvium exposed by excavation,so as to provide bearing capacity and deformation indicators,give suggestions on the foundation scheme,which has important reference significance for the development and utilization of similar engineering sites.
