摘　　要：“双碳”目标下,构建新型桩基是需要解决的重大课题。论文开展了不同相对密实度和加载高度下的桩基单调水平加载试验,分析水平承载力和土体刚度的变化规律对桩基承载特性的影响。结果表明,在相同水平荷载作用下,降低水平荷载加载高度会提升桩基水平承载力。场地相对密实度增加,桩周土体刚度增大,桩周土体水平抗剪能力越强。Under the two-carbon target,the construction of new pile foundation is a major issue to be solved.This paper carries out the monotonous horizontal loading test of pile foundation under different relative density and loading height,and analyzes the influence of the horizontal bearing capacity and soil stiffness on the bearing characteristics of pile foundation.The results show that under the same horizontal load action,reducing the horizontal load loading height will increase the horizontal bearing capacity of pile foundation.The relative density of the site increases,the stiffness of the soil around the pile increases,and the horizontal shear resistance of the soil around the pile is stronger.
