摘　　要：通过对型钢水泥土桩支护结构的侧向位移与其本身刚度、支撑刚度、地基土压力等关系的分析,考虑水泥土对荷载具有分担作用,并对围护结构体的刚度具有贡献,给出了型钢水泥土桩的抗弯刚度及围护桩、支撑和地基的相互作用的受力变形方程。由此,便于明确基坑开挖过程中,围护结构与土体相互作用产生的侧向变形。The relation of lateral deformation! of reinforced cement-soil pile supporting structure, the stiffness of supporting structure and braces and soil pressure is analyzed. In this paper, comidering the cement-soil can share load and make contribution to the stiffness of supporting structure to calculate reinforced cement-soil pile stiffness. The stress-deformation equation that supporting piles, braces and foundation soil interact is given. It explicit the lateral deformation produced by the interaction between supporting structure and soil during the process of digging excavation.
