变形的几何分析给出了变形体形状和尺寸变化的几何描述,它没有能对引起变形的原因作出解释。为了更好地监视建筑物的安全,对可能产生的变形作出预报,进而对设计理论和设计参数进行检验和修正,就必须对变形作出物理解释,确定变形体变形值和引起变形因子之间的函数关系。这一问题的解决一般采用回归分析法(统计的方法)与确定函数模型法。回归分析法利用过去的长期观测数据,通过统计规律来建立荷载-变形之间的函数关系,当引起变形体变形的因素较多且各因素之间又存在较复杂的相互影响时,这是一种较好 The geometric analysis of the deformation gives a geometric description of the shape and dimensions of the deformed body. It does not explain the cause of the deformation. In order to better monitor the safety of buildings, to forecast the possible deformation, and then to test and correct the design theory and design parameters, it is necessary to make a physical interpretation of the deformation, to determine the deformation deformation value and cause the deformation factor between Functional relationship. The solution to this problem generally uses regression analysis (statistical methods) and deterministic function model methods. The regression analysis method uses the long-term observation data of the past and establishes the functional relationship between load and deformation through statistical laws. When there are many factors that cause deformed body deformation and there are more complicated mutual influences among various factors, this is a Better
