| 中文摘要: |
| 基于“永临一体化”的深基坑内支撑结构是近年来迅速发展和推广的一种新型深基坑支护技术。本文依托合肥清三冲雨水调蓄池深基坑工程实践，在分析调蓄池地下主体结构和深基坑原内支撑结构特征的基础上，提出了一种仅通过对内支撑竖向高程的轻微调整技术，进而实现深基坑临时支护结构与调蓄池地下主体永久结构一体化的设计优化方案，并详细阐述了方案实施步骤。工程实施效果表明，调蓄池深基坑“永临一体化”支撑结构具有安全度高、经济性好、高效节能、绿色环保、建设周期短等诸多优势，工程建设整体效果良好。 |
| 英文摘要: |
| The deep foundation pit internal support structure combined permanent and temporary works is a new deep foundation pit support technology developed rapidly in recent years. Based on the Qing Sanchong deep foundation pit project for rainwater reservoir in Hefei，the underground main structure of the project and the characteristics of the original internal support structure of the deep foundation pit are analyzed，and an optimization scheme for the integration of the temporary support structure of the deep foundation pit and the temporary underground structure by slightly adjusting the vertical elevation of the internal support，as well as the implementation steps is proposed. It is proved that the optimization scheme is safe，economic，efficient，environment-friendly and the construction process is short. The effect of the construction is satisfactory. |
