详细介绍了路基剖面管沉降监测技术方法;结合监测数据对宽路基沉降变形规律进行了初步分析。结果表明,路基两侧竖向测斜管的水平位移呈现出明显的抛物线型特点,而宽路基水平测斜管的竖向位移呈现出明显的马鞍型特点。
The method of settlement monitoring of subgrade profile pipe is introduced in detail. The settlement regulation of wide subgrade is analyzed with the monitoring data. The results show that the horizontal displacement of the vertical inclinometer on both sides of the roadbed shows obvious parabolic characteristics, while the vertical displacement of the horizontal inclinometer on the roadbed shows obvious saddle-type characteristics.
