| 地下主体结构与支护结构相结合的深基坑支护设计，即利用地下结构梁板体系作为水平内支撑体系， 是一种高效节约的新式深基坑支护方案。结合工程条件和水文地质条件，详细论述了地下梁板结构替代水平 内支撑的深基坑支护设计方案。对水平结构与围护结构的连接设计、水平结构与竖向支承结构连接设计、出 土进料口设计等关键施工技术进行了详细说明并论述施工流程，最后分析实地监测数据，得到了地下结构梁 板替代内支撑设计下深基坑的部分变形特征和规律，论证了新型深基坑支护设计与施工的安全性与可行性。 |
| 英文摘要: |
| The deep foundation pit support combining underground main structure and support structure，i. e. ，using the underground beam-plate system as the horizontal internal support system，is an efficient，economical scheme. Considering both engineering conditions and hydrogeological conditions，such scheme is discussed，and the key construction techniques such as the connection design of the horizontal structure and the enclosure structure，the connection design of the horizontal structure and the vertical support structure，and the design of excavation are explained，and the construction process is scheduled. The monitoring data are analyzed to obtain the deformation characteristics and laws of the deep foundation pit with the underground beam-plate structure instead of the internal support design. The feasibility of the scheme as well as the safety of the construction are demonstrated. |
