摘　　要：复合型土钉墙防护是通过预加固桩对边坡进行预加固后,施水泥土搅拌桩作土钉墙,使土钉墙与预加固桩共同承受边坡滑坡推力,从而达到加固边坡的效果。文章依托工程实例,介绍了复合型土钉墙的施工材料及机具,阐述了复合型土钉墙施工工艺流程,并提出了相应的施工质量控制措施。The procedure of building a Compound Soil-nail Wall is first to use piles to enhance side slope,then make concrete mixture pile as soil-nail wall,and let soil-nail wall and Pre-reinforcement pile common bear the Landslide thrust.Taking the construction prac-tice as example,the article introduces the construction material and equipment and the pro-duction process of Compoud soi-nail wall.Corresponding construction quality control meas-ures are also proposed.
