摘要
分析了深厚软土对夯扩桩受力和变形的影响,主要包括:由于软土侧压力的作用造成承台桩侧移或剪断或弯曲,沉桩引起的挤土效应和地面隆起,增大了桩的负摩阻力,降低了桩基的稳定性。探讨了为减小上述影响应采取的设计和施工措施。
The influences on stress and deformation of ramming under-expanded by deep soft soil are analyzed. These influences include pile appearing lateral displacement or curve or fracture caused by lateral pressure of soft soil, soil squeezing effect and ground swell during pile driving and so on. All kinds of measures are discussed from design to practice in order to reduce above-mentioned influences.
