摘要:
采用可视化室内模型试验方法,对垂直受荷单桩桩周土体位移场、应变场发展规律及破坏性状进行较为深入研究。结果表明:桩侧土体变形影响范围为(3~4)b(b为方桩边长),桩端下土体影响范围为(5~6)b; 单桩桩侧土体最大剪应变由桩身上部逐渐向桩身下部延伸,桩端以上(3~4)b截面附近存在侧阻力弱化区; 单桩破坏面由桩侧土体剪切滑动面、桩端鼻锥状弹性核及桩端附近的2片剪切滑动面组成。
Abstract:
The change regulation of soil displacement and strain field,and the destruction behavior of single pile under vertical loads were studied by a visualization model method.The results showed that the affected area of pile lateral deformation was(3-4)b(b was the side length)and that of pile tip deformation was(5-6)b.The maximal shear strain extended from top to bottom of the pile body,and a frictional resistance weakening area existed above the pile tip section(3-4)b.Single pile damage plane was composed of shear sliding surfaces near pile side,pile tip nose cone-shaped elastic core and two shear sliding surfaces near pile tip.
