| 将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。通过结合具体工程,考虑水文地质条件,详细论述了地下结构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的说明,并对施工流程进行了论述。最后对实地监测数据进行分析,得到了地下结构梁板替代内支撑设计下深基坑的一些变形特征和变形规律,论证了新型深基坑支护设计与施工的安全性与可行性。 |

| The deep excavation support design that combines the permanent underground structure and the supporting structure, that is, using the beam-slab system of the underground structure as the horizontal internal brace system, is a new, efficient and economical deep excavation support scheme. By combining specific projects and considering hydrogeological conditions, design scheme of deep foundation pit support with underground structure beam-slab structure instead of horizontal internal brace. The key construction technologies 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 excavation design are explained in detail, and the construction process is explained. Analyze field monitoring data. Some deformation characteristics of deep excavations under the design of combining horizontal internal brace and underground permanent structure are analyzed, and the safety and feasibility of the new type of deep excavation support design and construction are demonstrated. Some issues that need to be studied further are put forward for this new type of deep excavation design method for reference. |
