合肥至蚌埠客运专线窑河特大桥工程极软岩承载力的确定与分析

Determination and analysis of soft rock bearing capacity of Yaohe Bridge along railway dedicated passenger line from Hefei to Bengbu

结合合肥—蚌埠客运专线窑河特大桥工程中的极软岩(泥质砂岩),通过多种理论方法和勘察测试手段,对如何确定极软岩地基的承载力进行分析与探讨,总结出勘察经验与方法,并在今后的勘察工作中应用。加强分析研究这些方法和手段,扬长避短,使之能够较全面地反映极软岩的物理力学性质,能较准确地确定极软岩的地基承载力。对该岩体的工程地质特征,尤其是承载力的确定具有重要的实际意义。

In terms of the soft rock（muddy sandstone） encounterd during the engineering construction of Yaohe Bridge along railway dedicated passenger line from Hefei to Bengbu,through several theoretic methods and exploration manners,the author discussed and analyzed the determination of foundation bearing capacity for the soft rock,summarized the experience and methods,reflected the physical and mechanic characters of the soft rock.The above determination was of practical significance to decide the engineering geological properties of the rock mass.
