摘　　要：衡重式路肩挡墙是高填方路基广泛采用的支挡结构形式之一。结合某山区公路改建工程,对k2770+350^+450衡重式挡墙的变形及受力情况进行了现场监测。监测结果表明,衡重式挡墙的变形及受力与填方断面形式、填土材料的物理力学性质、施工方法、工作环境等诸多因素有关,在工程完成后的较长一时段内,填土与挡墙的相互作用仍对结构的变形有着一定的影响。Gravity balanced retainning wall is one of the widely used structures for tall backfilled embankments. Described in this paper is the field monitoring of a gravity balanced retaining wall during road reconstruction in a mountain area. Data collected showed that deformations and loading conditions to the wall were ＇affected by many factors such as geometry of the cross section of backfill, properties of the backfill materials, construction procedures, environment, etc. Even in a relatively long period after its completion, interaction between the backfill and the wall can still be detected.
