摘要: 膨胀土“吸水膨胀，失水收缩”的特性对实际工程影响极大，与土体的稳定性密切相关。文章以“南水北调中线某渠段渠坡沉降变形”为依托，根据工程设计资料以及现场监测数据采用Settle3D模拟软件，建立渠坡模型，分工况模拟渠坡沉降变形情况，探究渠坡沉降变形机理并提出针对性的防治对策。研究结果表明：渠坡自运行以来产生较大沉降的主次原因依次分别为：地下水大幅升降、渠道水大幅度升降、堤身自身沉降；分析渠坡整体沉降变化与地下水位和渠道水位有关。
Abstract: The characteristics of expansive soil, “swell-on-wetting, shrink-on-drying”, have a great impact on the actual engineering and are closely related to the stability of the soil. Based on the “settlement and deformation of a canal slope in a canal section of the middle line of the South-to-North Water Diversion Project”, this paper uses Settle3D simulation software according to the engineering design data and on-site monitoring data to establish a canal slope model, simulates the settlement and deformation of the canal slope under different conditions, explores the settlement and deformation mechanism of the canal slope, and proposes targeted prevention and control measures. The results show that the main and secondary reasons for the large settlement of the canal slope since its operation are as follows: the large rise and fall of groundwater, the large rise and fall of channel water, and the settlement of the embankment itself. The analysis of the overall settlement change of the canal slope is related to the groundwater level and the channel water level.
