高等级公路测设长度变形控制的研究

Research on Control of Length Deformation in High Road Layout

根据高等级公路测设长度变形的特点,通过对控制长度变形的抵偿投影面和抵偿投影带确定方法的研究,获取了一种较为简便的选取具有高程抵偿面的任意带高斯投影平面直角坐标系的确定方法,经实例验证,应用该种方法能较好地抵偿长度变形。

According to the characteristics of length deformation in high road layout, a simple and convenient method which can be used to determine Gauss projection plane rectangular coordinate system of arbitrary zone which has a elevation compensating plane is obtained by studying the method of determining compensating projection plane and projection zone of controling length deformation. The example shows that appling the method can compensate length deformation better.
