曲线拟合法监测圆形建筑物倾斜变形

The Curve-fitting Method for Monitoring InclinationDeformation of Cylindrical Structures

从最小二乘原理出发,分析和讨论了曲线拟合法监测圆形建筑物倾斜变形的原理、数学模型和实现方法等全过程。利用便携机配合全站仪进行坐标测量,很好地解决了测量误差及建筑物自身变形问题。与传统的建筑物倾斜观测方法相比,具有实施简单、功能优越、准确可靠的特点,是一种有效的跟踪监测方法,具有一定的实用价值。

The least-squares method is adopted to analyze and discuss the total process of curve-fit-ting method for monitor inclination deformation of cylindrical structures, including its theorem, mathematical model and realization method. As the measurement of coordinates is made by note-book computers and total station instruments, the problems of survey error and self-deformation are satisfactorily solved. It is shown that the method is simple, accurate and reliable with superb functions; therefore, it is an effective truck-monitoring method with great practical values.
