摘要
针对越南河内-海防高速公路某标段高填方路堤边坡稳定问题,运用松尾方法对本工程典型断面进行路堤边坡稳定分析,并结合现场实测数据对该问题进行了探讨和研究。研究表明,在堆载过程中,各断面路堤边坡处于稳定安全状态。通过Morgenstem-Price极限平衡稳定分析方法,运用Geo-Studio 2007软件计算了典型断面的稳定安全系数。计算结果表明,路堤边坡采用1∶2坡率施工时较合理。研究成果为路堤边坡稳定的工程问题提供了借鉴。
Aiming at the problem of different highway soft foundation processing mode transition section and high-filled embankment and slope stability of the Hanoi-Haiphong Expressway section in Vietnam,this paper analyzed the typical section of the project through Minoru Matsuo＇method and the field data. The research results showed that in heaping process,the section of subgrade slope was stable and secure. Through Morgenstem-Price limit equilibrium stability analysis,the stability safety factor of typical section has been calculated by using Geo-Studio 2007 software. The results showed that it＇s reasonable when the slope rate of slope was 1∶2. The research results can provide good reference for engineering problems about subgrade slope stability.
