| 摘 要： | 针对某深基坑施工场地狭小、周边环境复杂、基坑支护施工难度大的特点，采用了技术与经济均合理的双排桩基坑支护方案。在分析工程场地环境条件的基础上，设计选择双排桩加锚杆支护的体系，护坡桩施工采用人工挖孔的成孔工艺，并在前排护坡桩桩顶设置了位移观测点。结果显示，施工过程中，该边坡与周边环境安全稳定，边坡最大位移在规范允许的范围之内。作为双排桩支护成功案例，可为类似工程提供借鉴。 |

| Abstract: | The construction site of a deep foundation pit is narrow and the surrounding environments are complex, the work difficulty for supporting foundation pit is big, the technical and economic reasonable foundation pit supporting scheme with double-row piles was adopted. During foundation pit excavation and the use of pit, security and stability of slope and the surrounding environments were insured, the monitored maximum displacement was within the range of specified value. As a double-row pile supporting successful cases, it provides practical experience for reference for similar projects. |
