摘要：针对河北工程区粘土段路堤为研究对象，通过结合地质条件、水文条件、自然环境等对该粘土区段内路堤沉降进行现场监测及分析，并对路堤沉降提出解决措施。结果表明：在路基施工过程中应着重注意路基中心处沉降变化。各个监测点沉降值均随着时间的变化表现出先增大后趋于稳定的趋势；且各监测面路肩沉降均小于路基处；在路堤施工过程中应加强过程质量管控，及时施作排水和防护设施，并采取冲击碾压补强和土工格栅铺设等工艺措施，有效防治路基的沉降。
Abstract: Taking the clay section of the embankment in Hebei engineering area as the research object, the settlement of the embankment in this clay section was monitored and analyzed on site by combining geological conditions, hydrological conditions, natural environment, etc., and solutions were proposed for the settlement of the embankment. The results indicate that special attention should be paid to the settlement changes at the center of the roadbed during the construction process. The settlement values of each monitoring point show a trend of first increasing and then stabilizing over time; And the settlement of road shoulders on each monitoring surface is smaller than that at the roadbed; During the construction process of embankments, it is necessary to strengthen process quality control, timely implement drainage and protective facilities, and adopt process measures such as impact rolling reinforcement and geogrid laying to effectively prevent and control the settlement of the roadbed.
