摘要/Abstract

摘要： 结合发生于京福高速公路南平段土地洋大桥邻近的高填方残积土路堤滑塌灾害，着重分析了高填方残积土路堤滑塌与降雨的关系。对强降雨入渗导致高填方残积土路堤滑塌机理进行了相关参数分析，结果表明，渗流主要分布在靠近原地面处，此处容易形成软弱滑动面，造成滑塌。还探讨了引起滑塌的其他潜在因素如高填方路堤填土的土质特性、压实度以及湿化变形等，并提出了整治方案，为高填方路堤的填筑设计、控制施工质量提供了依据。

Abstract: Residual soil filled embankment failures have been the major part of landslide. The landslide event occurred at the filled embankment adjacent to the bridge abutment of Tudiyang Bridge at Nanping Section of Beijing-Fuzhou Expressway has been analyzed; and some factors affected on the residual soil filled embankment failure have been analyzed. The rainfall infiltration, as the most important factor, affected on this landslide event. Based on the parametric evaluation of the residual soil filled embankment failure, such mechanism analysis of filled embankment stability has been given. And the landslide were also caused by other triggering factors including the compacting factor of residual filled soil, the residual soil characteristics and the slaking deformation. The results offer engineering treatments of designing the high residual soil filled embankment and controlling the quality of construction.

Key words: road embankment, rainfall, residual soil
