最小二乘法在施工放线方面的应用

Application of Least Square Method in Construction Putting Lines

对外型为曲线的钢筋混凝土结构,施工放线前,利用最小二乘法原理,根据已给出的工程数据,确定出构件轮廓曲线的近似函数,使该函数所代表曲线上各点精度满足施工要求,再利用这个近似函数对构件进行放线。

For the reinforced concrete whose appearance is a curve, before putting lines in the construction, we should make use of Least Square Method based on the construction data given to determine approximate function of component抯 outline curve and make every point that the function represents in the curve accurately meet the requirements of construction. Then we may use this approximate function to put lines.
