摘要

摘要: 劲性水泥土连续墙由相互交接的搅拌桩和内插的型钢组成,墙后水土压力引起的墙体弯矩主要由型钢承担,水泥土对型钢的承载能力具有重要作用。通过分析型钢的受弯整体稳定性和型钢间水泥土的受力状态,探讨了水泥土约束作用对型钢整体稳定承载力的影响,对劲性水泥土连续墙中水泥土的强度提出了控制原则,并分析了施工偏差对型钢受力带来的影响,提出了劲性水泥土连续墙设计和施工的技术控制措施。

Abstract: The reinforced cement-soil mixing wall is composed of cement-soil piles connecting each other and shape steel. The moment induced by soil and water pressure is carried mostly by the shape steel. The cement-soil has contributed to carrying capacity of the shape steel. By analyzing the overall stability of the shape steel and mechanical status of cement-soil the effect of restriction of cement-soil on unitary stable capacity of the shape steel is studied. The principle about how to use the strength of cement-soil is proposed. The influence of constructing error on bearing force of the shape steel is analyzed. The technical measures in the design and construction of reinforced cement-soil mixing wall are proposed.
