摘　　要：以某高速公路实地高填方路基生成的侧滑问题为案例,在解析其生成的因由的前提下,提出了将防滑钢管桩+锚杆+钻孔注浆复合稳固工艺等应用于施工进程中,并在实地作业时配置了应力和位移测控装置,对其加固品质开展评估。通过对试验数据的解析,证明了这种复合地基的防滑性和稳固性能极其优良。This paper takes the sideslip problem caused by high filling subgrade of a highway as an example, on the premise of analyzing the causes of its formation, the composite stabilization technology of non-slip steel pipe pile + anchor bolt + borehole grouting is proposed to be applied in the construction process. In addition, the stress and displacement measuring and controlling device is equipped in the field operation to evaluate its reinforcement quality. By analyzing the test data, it is proved that the composite foundation has excellent anti-skid and stability performance.
