| 摘 要： | 利用灰色理论,对影响桩基础极限承载力的因子：桩周土容重、压缩模量、粘滞力、内摩擦角以及桩长和桩径进行灰色关联分析。分析结果表明：对桩基极限承载力影响最大的因子是桩周土粘滞力,其次是土的压缩模量、桩体的长度、桩底直径、土的内摩擦角,影响最小的因子是桩周土容重。

| Abstract: | The influencing factors of ultimate bearing capacity of pile foundation are analyzed by Grey Sys- tern Theory suth as bulk density of soil around pile,soil compression modulus,cohesion,internal friction angle, pile length and pile diameter.The analysis result shows that the first factor influencing ultimate capacity of pile foundation is soil cohesion;the following are soil compression modulus,pile diameter,pile length and internal friction angle.Bulk density of soil around pile has the least influence. |
