摘要
在地质条件复杂的岸段,只采用经验性方法进行塌岸预测是不能满足要求的,本文在分析冰水堆积物特性的基础上,通过三维数值计算方法研究了雅泸高速公路K92+332～765段,该段路基边坡在水库蓄水后的稳定性,直观的揭示出该段路基边坡在库水浸泡后的变形情况,得出蓄水后岸坡岩土体可能产生失稳破坏的范围主要是松散层、稍密层和中密层。
After analyzing the specialties of outwash deposits, by means of three-dimensional numerical simulation, the author studied the stability of the K92＋332-765 roadbed slope in Ya-Lu expressway and measures for regulation. By this way, the deformation of the roadbed slope and the feasibility of preset measures for regulation were illustrated intuitionally and it was made out that the main destroying soil mass is relax, slightly dense and middle dense soil mass. All the above will provide valuable reference to the reinforcing.
