本文提出的由水泥土和混凝土两种材料组成的劲性搅拌桩解决了搅拌桩强度、刚度不足的问题，使搅拌桩桩侧阻力得以充分发挥。通过第一批 24根原型桩系列对比试验，证实芯长和含芯率适当的劲性搅拌桩平均具有高于混凝土桩 30％以上的承载力，并初步掌握了劲性搅拌桩的载荷特性、工作机理和成桩工艺。
In this paper, a stiff mixing pile composed of two kinds of cemented soil and concrete is used to solve the problem of insufficient strength and rigidity of the mixing pile, so that the lateral resistance of the mixing pile can be fully exerted. Through the first batch of 24 prototype pile series comparison test, it is confirmed that the core length and the core content of the appropriate mixing force pile has an average of 30% higher than the concrete pile bearing capacity, and initially grasped the load characteristics of the stiff mixing pile, Working mechanism and pile technology.
