地形对黄土高填方路堤沉降的影响

以太原市太行路高填方路段为研究对象,通过沉降观测,研究黄土地区高填方路堤的沉降过程及其发展变化规律,从而了解到影响高填方路堤沉降的影响因素。由于该高填方路堤地形的特殊性,通过控制施工速率、填土高度、地基土质和填土容重等参数,通过对该路段工后沉降的观测,较好的研究了地形对高填方路堤沉降的影响。观测结果及分析表明:对于黄土地区高填方路堤,地形因素对沉降量的影响不容忽视。通过研究也为高填方路堤填筑方案的选取提供依据。

Effect ofS terrain on theSsettlement of high fill embankmentSin Loess

Alongside the high-fill in TaiHang road, in TaiYuan as the research object, S through settlement observation, loess areas of high embankment settlement process development and its variation, thus understand factors that influence high embankment settlement. Due to the special nature of the project high fill embankment terrain, by controlling the rate of construction, filling height, foundation soil and backfill density and Based on the observationSof the roadSsettlement, study the influence of topography onSthe settlement of high fill embankment. Observations and analysis show that: for loess area high embankment, the impact on the settlement of the terrain factors can not be ignored. Also provide the basis for select high fill embankment programs through research.
