摘要
阐述了劲性水泥土连续墙的工作机理,指出水泥土对荷载具有分担作用并对结构体的刚度具有贡献,而且这种分担作用和贡献将随荷载的变化而变化。将劲性水泥土连续墙体在荷载作用下的变形过程分为5个阶段,分析了各阶段结构有效截面和截面应力分布的演变情况,推导了在工程应力允许范围内连续墙结构刚度的计算式,并通过试验验证了计算方法的合理性。
The working mechanism of reinforced continuous cement-soil wall is described, and it is pointed out that the cement soil can share load and make contribution to the stiffness of continuous wall structure. The behaviour of cement soil is varied with applies load. The deforming process of reinforced continuous cement-soil wall under the load is divided into 5 phases. The evolution of efficient section and stress distribution in every phase is analyzed. The stiffness formula of continuous wall is derived and proved by test.
