| 中文摘要:在济南东舍坊项目深基坑工程中，同一深基坑支护工程采用桩锚、悬臂桩、复合土钉墙3种支护方式。对基坑支护设计、监测等内容进行了介绍。监测结果表明，3种支护方式都能满足基坑的安全性要求，符合设计；说明3种支护方式应用于同一深基坑中效果非常好，同时节省了工程造价，缩短了工期。通过变形对比分析，对于本基坑而言，桩锚支护对控制边坡变形效果最好，悬臂桩次之，复合土钉墙最不利。 |

| Abstract:In the Jinan Dongshefang deep foundation pit works, three kinds of support methods were used in the same support project: the pile anchor, the cantilever pile, and the composite soil nailing wall. The design and monitoring of the foundation pit support are introduced. The monitoring results show that all three support methods can meet the safety requirements of the foundation pit and meet the design requirements; indicating that the three support methods applied to the same deep foundation pit worked very well, saved the project cost, and cut short the construction period. Comparison of deformation demonstrates that the pile-anchor support has the best effect on controlling the deformation of the slope, followed by the cantilever pile; while the composite soil nailing wall is the most disadvantageous. |
