摘要
劲性搅拌桩是在水泥土搅拌桩内插入刚性芯桩形成的一种桩型,具有承载力高、造价低等优点,适用于软粘土地基。本文结合设计、试验和工程经验,讨论了劲性搅拌桩的破坏模式,并提出了劲性搅拌桩的优化设计方法,为设计和施工提供可靠依据。
Reinforced mixing pile is formed by inserting a rigid core pile into the cement mixing pile. High bearing capacity and low cost are its merits. It is applicable to the ground based of soft soil. According to experiences of its design, field experimentation and construction, this paper discusses the failure mode of the reinforced mixing pile, and brings forward the optimization design method of the reinforced mixing pile, which could provide a reliable basis for the design and construction of the reinforced mixing pile.
