摘要:
桩锚支护结构主要依靠锚杆预应力承载并显著减小坑壁侧移,土钉支护主要依靠对坑壁土体的加强来减小土体侧压力并承载,将二者有机地联合起来成为一个共同承载的整体是目前基坑支护工程中常用的结构形式.在坑壁土压力及地面超载作用下,桩锚与土钉作为一个整体共同抵抗荷载和变形,但实际工程中基坑支护结构的可用空间常受到场地限制.根据桩锚和土钉联合支护结构的受力特点、施工特点及设计规范的相应要求,考虑预应力锚杆自由段长度与土钉直线破裂面间的协调关系,按照总锚固力等效原则,研究总结了受限的联合支护结构的设计计算方法,对受场地条件限制的基坑工程支护和开挖具有一定的理论指导意义.
Abstract:
The pile anchor support structure mainly relies on the anchor prestressed bearing and significantly reducing the lateral shift of the pit wall, and the soil nail support mainly relies on the strengthening of the soil of the pit wall to reduce the pressure and bearing on the soil side, and organically uniting the two into a common bearing whole is a commonly used structural form in the current foundation pit support engineering. Under the action of earth pressure and ground overload on the pit wall, the pile anchor and the soil nail work together to resist the load and deformation, but the available space of the foundation pit support structure in the actual project is often limited by the site. According to the force characteristics, construction characteristics and corresponding requirements of the design code of the joint support structure of pile anchor and soil nail, considering the coordination relationship between the length of the free section of the prestressed bolt and the straight fracture surface of the soil nail, and according to the principle of total anchoring force equivalence, the design and calculation method of the restricted joint support structure is studied, which has certain theoretical guiding significance for the support and excavation of foundation pit engineering limited by site conditions.
