| 摘 要： | 详细介绍了某工程应用土钉墙联合钢板桩加一道内支撑的支护技术成功围护深基坑的实例。通过该工程实例,对于开挖深度在7.0～10.0 m范围的深基坑,在周边环境及地质条件允许的情况下,建议采用土钉墙联合排桩加一道内支撑的复合围护方式。与传统的支护形式——排桩加两道水平内支撑体系相比,前者在安全、造价及工期上具有相当的优势。

| Abstract: | A successful application of bracing of foundation pits using soil nail walls and steel sheet-pile walls with an internal bearing beam was introduced.According to the engineering project,the above bracing method was suggested in the 7.0 to 10.0 m-deep foundation pit excavation if the surrounding building,underground pipes and geological conditions were permitted.Compared with the common method of sheet pile-braced cuts with two internal bearing beams,the proposed bracing method is dominant in safety,cost and engineering duration. |
