在软土边坡及深基坑工程中,加劲桩对控制土坡变形和稳定性的作用比常规的锚杆(索)有更多优势,加劲桩的锚固力主要依靠锚固体与周围土体之间的摩阻力提供。利用Mindlin位移解导出加劲桩加筋体黏结段受力的理论解,通过抗拔力传递过程中,加筋体与锚锭板对水泥土锚固体接触应力分布的变化,分析多个锚锭板对加劲桩承载力和变形量的影响,建立了锚锭板分布对加劲桩抗拔承载力的定量作用,并经现场试验验证。 In soft soil slopes and deep foundation pit projects, the effect of stiffened pile on deformation and stability of control slope is more than conventional anchor (cable). The anchoring force of stiffened pile mainly depends on the strength of anchorage and surrounding soil The friction between the offers. Based on Mindlin displacement solution, the theoretical solution of the stress in the stiffened section of the stiffened pile was deduced. During the process of transferring the buckling force, the stress distribution of the anchored body with the anchor plate was analyzed. The effect of the distribution of the anchor plate on the pull-out bearing capacity of the stiffened pile is established, which is verified by the field test.
