| 摘 要： | 针对兰州地区的湿陷性黄土，通过两根实际工程桩实测出正常使用状态下支护桩桩身在不同开挖深度的弯矩分布，推导了桩身剪力和土压力，并与设计值进行了比较．重点分析了悬臂式支护桩在正常使用状态下的桩身内力和所受土压力的分布情形，揭示了目前深基坑支护桩设计中存在的主要问题及其内在因素，提出了土压力分布图形．

| Abstract: | To counter the collapsible loss in Lanzhou region,the distribution of earth pressure and shear force of retaining pile is derived based on the distribution of banding moment obtained from the experiment of two piles with different depth of excavation.The calculation values is compared with the values obtained from experiment.The distribution of earth pressure and internal forces of pile body under normal condition is emphatically analyzed. The main defects and related reasons in the design method of pile for retaining deep foundation pit are brought into light,and an earth pressure distribution graph is provided for reference of design. |
