摘要： 针对高填方软土路基的填方高度大、地基承载能力低以及侧向变形与普通填方路基侧向变形的差异，基于绵阳～遂宁高速公路高填软土路基段深层水平位移监测的实践，发现常规的监测方法在高填软土路基的深层水平位移监测中存在一些问题。在对这些问题及原因进行深入分析后，提出了相应的改善方法与处理措施，包括测斜管埋设位置的选择、孔壁回填、偏转及扭转的处理、误差控制、协调变形分析等，为西南地区特殊地质地形条件下的高填软土路基深层水平位移监测提供一定的参考。

Abstract: Based on the monitoring of deep horizontal displacement in soft soil subgrade with high embankment in southwest region, there were some problems to monitoring its deep horizontal displacement by the conventional method. According to its characteristics such as high embankment, low bearing capacity and the different lateral deformation, some improving measurement were proposed including the location chosen of inclinometer inbuilt, backfilling of inclinometer hole, treatment of deflection and twist, error control, compatible deformation analysis, which was as the preference for similar engineering in southwest region.
