摘　　要：对于一些开挖深度不大的基坑工程,可以采用在受拉区加入型钢的加筋水泥土挡墙支护形式。这样可以充分发挥型钢的高抗拉强度和水泥土较高的受压强度,使得墙厚大大减少,节省材料。本文主要利用大型通用有限元软件,研究了这一支护结构形式在不同型钢位置、墙体厚度、墙体强度等条件下水泥土墙和型钢的作用机理。When the depth of excavation is not too deep, reinforced cemented soil retaining walls can be used, where shaped steel is applied in the zone subjected to tensile force. The thickness of this composite shaped steel-cemented soil wall can be significantly reduced by taking the advantage of the shaped steel of high tensile strength and the cemented soil of comparatively high compressive strength. By using FEM the interaction between shaped and cemented soil is studied with regard to different positions of the shaped steel in the composite wall, different thicknesses of the composite wall and different cemented soil strengths.
