摘　　要：以朔黄铁路为背景,通过对朔黄铁路温塘河特大桥0号桥台锥坡坍塌、台后路基填土溜坍、路基下沉等病害的分析及治理进行研究,提出相应的治理措施:采用上部注浆+下部边坡斜向旋喷桩的综合整治措施。该综合治理措施效果显著,既达到了整治效果、又降低了对既有线运营的影响,对既有铁路桥台锥坡、路基加固工程有一定的借鉴意义。Based on the background of ShuoHuang railway, research on the disease and treatment scheme of cone slope collapse, subgrade slides and subgrade sinks for No.0 abutment of Wengtang river bridge in ShuoHuang railway. The corresponding control measures are put forward： the comprehensive control measures of the upper grouting ＋ the lower slope inclined jet grouting pile are adopted. The effect of this measure is remarkable, which not only achieves the effect ofremediation, but also reduces the influence on the operation of the existing railway. It has certain reference significance to the existing railway abutment cone and embankment reinforcement.
