摘要
随着高层建筑越建越高,采用筏型基础或桩筏基础时,筏板的厚度也不断增大。由于工程界中对于厚筏基础缺少研究,不了解其具体的受力特性,在厚筏基础设计方面缺乏成熟的设计理论和计算方法,厚筏基础仍按常规筏基的设计方法进行设计,往往造成筏板过厚,使基础造价过高,产生很大的浪费。
     本文根据高层建筑上部结构、基础和地基共同作用的基本原理,考虑了多种因素的影响,建立模型,用数值计算方法研究了上部结构,筏板厚度,裙房跨数等因素对基础沉降,基底应力,框架内力的影响,分析了厚筏基础的基本受力特性。
     通过大量的数值模拟分析,对高层建筑与裙房在整体连接的情况下上部结构,基础与地基的共同作用问题进行了研究。并结合数值分析,得出了筏基变形和地基反力分布特征,指出大底盘框架厚筏体系的工程性质同高层建筑与其连接的裙房基础密切相关的,并总结了共同作用的有效范围。
With the increase of height of tall buildings in our country, the thickness of raft become larger and larger when raft foundation or pile-raft foundation is adopted. Owning to lack of research on properties of thick-raft foundation, the appropriate assigning principles and calculation methods are lacked in engineering field. Instead the traditional design methods that lack accuracy are used in designing thick-raft foundation. It usually results in too thick raft, and make the cost of foundation very high.
    In this paper, on the base of the interactive principles of superstructure, base and soil, Many factors are considered. The method corresponds to real foundation working conditions. By research done on a structural model with numerical calculation method. The effects of some factors, such as superstructure stiffness, thickness of raft, compressive modular constant of soil, suspended width of raft and raft concrete intensity, on the working behavior of thick-raft foundation are analyzed. And in coordination with data obtained from an engineering test on site, the regularities of foundation settlement and the distribution properties of pile reaction, soil reaction and steel stress in raft, of the pile-(thick)raft tested are analyzed. In the same time, the calculating results with finite element method almost correspond with measured results.
    The interaction of low-storied podiums with a high-rise building is studied through some simulation tests. Really, it is studied on the interaction of the frame structure,
    
    
    
    thick raft foundation, and soil. The deformation and reaction of the thick raft foundation can be measured. It is obtained from the simulation tests and numerical analysis. It is shown that the engineering characteristics of whole raft foundation are closely related with the span of low -storied podium nearby the high-rise building. A new conception of the effective range of interaction is proposed in this paper.
