| 以天津市滨海新区中央大道海河隧道工程临水深基坑为研究背景，该深基坑最大深度达27.5 m，临近海河，处于滨海相软土地质区域，施工环境较复杂。为了保证深基坑的施工安全，着重进行支撑体系施工技术研究。通过技术研究，采用了受力科学合理的工具式组合支撑体系，保证了超深基坑施工安全质量，为我国深基坑的支撑体系设计与施工提供了参考依据与借鉴经验。 |
| 英文摘要: |
| The deep foundation pit of Haihe River Tunnel of Central Avenue in Tianjin Binhai District has a the maximum depth of 27.5 m. It is adjacent to the river, and located in a marine soft soil geological region, thus the construction environment is complex. In order to ensure the construction safety of the deep foundation pit, emphasis is placed on the construction technology of the supporting system. Through technical research, using the scientific and reasonable tool type combined support system, the quality and safety of super deep foundation pit construction is ensured, which may provide some reference for the design and construction of supporting system of deep foundation pits in China. |
