摘　　要：本文介绍一种新型的拱形支护结构的应用实例。该结构是把水泥土搅拌桩排列成拱形，使其受力合理，形成一种既挡土又防渗且位移很小的支护结构．在马钢１２０多米长的料槽基坑中，开挖１１．７ｍ，创造了在软土地基上用水泥土搅拌桩护壁的最大深度，取得了很好的经济和技术效果．An example of a new arched supporting structure is described in this paper, by which the soil cement mixing piles can be arranged into arches of stressing properly, and thus forming a retaining and impervious supporting structure with a small displacement . A 11.7m depth and 120mm long foundation pit was excavted for Ma Anshan Iron and Steel Cormpany, which was the largest supporting depth by soil cement mixing piles in a soft soil ground. Excellent results of economy and technology have been obtained.
