【摘要】 通过对天津沿海软土地基 77根灌注桩的静载荷试验资料对比分析发现 :对于软土地基上桩基工程 ,单桩承载力的发挥存在明显的深度效应 ,并且与 Meyerhof,G.G,陈强华 ,周镜等人提出的砂土和硬粘土地基上单桩承载力的深度效应有明显区别 ,天津沿海软土地基的临界桩长应为 33～ 45倍桩径 ,同时临界桩长受地基土的抗剪强度影响更多还原

【Abstract】 Through the analysis of pile’s static load experiment materials in the seashore soft-soil of number 77 to Tianjin,the results had been found that the single pile utmost bearing capacity has distinctly depth influence in the soft-soil foundation.The pile critical length is difference between of the soft-soil of Tianjin,sand and hard-soil by the Meyerhof,Chen Qianghua and Zhoujing.The pile critical length in the Tianjin soft-soil is the thirty three to forty five times as large as pile diameter.Meanwhile,the pile critical length can be influence by the soil shear strength.更多还原
