Soft soil foundation axial force servo profile steel-concrete combined supporting structure and construction method
The invention relates to a soft soil foundation axial force servo profile steel-concrete combined supporting structure and a construction method, and solves the problems that in foundation pit engineering construction, long time is often needed before the concrete strength reaches the design requirement, and deformation of an enclosure structure is easily caused. One span, closest to an underground diaphragm wall, of a basement of the structure is a side span, a passive reinforcing area is arranged between the side span and the underground diaphragm wall, a beam body is arranged closest to the outer side of the side span to form a structure side beam, and a beam body perpendicular to the structure side beam is a side span structure main beam; according to the multi-layer basement, a basement top plate structural beam plate, the multi-layer basement and a basement bottom plate are sequentially arranged on the inner side of a structural boundary beam from top to bottom, for each layer of basement, the structural beam plate is arranged on the inner side of the structural boundary beam, and a passive reinforcing area on the outer side of the structural boundary beam is an axial force servo profile steel support. Aiming at the problems that the concrete support is long in construction period and low in forming strength, and the concrete support is serious in creep and shrinkage deformation and the like, the servo profile steel-concrete combined support system capable of solving the problem of deformation control of the foundation pit support of the soft soil foundation is formed by combining the advantages of the profile steel support in the aspects of rapid construction and construction prestress.
本发明涉及一种软土地基轴力伺服型钢‑混凝土组合支撑结构及施工方法，解决基坑工程建筑中，混凝土强度达到设计要求前往往需要较长时间，容易造成围护结构变形的问题。本结构地下室最靠地下连续墙的一跨为边跨，所述边跨和地下连续墙之间为被动加固区，边跨最靠外侧设置梁体形成结构边梁，与结构边梁垂直的梁体为边跨结构主梁；所述多层地下室在结构边梁内侧从上到下依次设置地下室顶板结构梁板，多层地下室以及地下室底板，对于每层地下室，结构边梁的内侧为结构梁板，结构边梁外侧的被动加固区为轴力伺服型钢支撑。本结构针对混凝土支撑施工周期长、形成强度慢及混凝土支撑徐变、收缩变形严重等问题，结合型钢支撑在快速施工及施工预应力方面的优势，将两者结合，形成可解决软土地基基坑围护变形控制问题的伺服型钢‑混凝土组合支撑体系。
