基于三次样条函数的倾角仪测量桥梁挠度法

摘要

介绍了利用样条函数中的三次样条法，在桥梁若干测点倾角值已知的情况下，通过计算获得测点处的挠度值的方法，此方法适用性强、测量精度高、工作量小，对于大中型桥梁的挠度监测具有较好的应用价值。其分析方法可供同类型桥梁挠度计算方法借鉴。%This paper describes the use of cubic-spline function method, known in the Angle of the value of some covers circumstance, calculated by measuring deflection value analysis method, this method has high precision, small amount, widely used in large and medium-sized Bridges etc, and has better deflection monitoring application value.The analysis method for calculating method with type bridge deflection.
