摘要
介绍了采用CASIOfx - 4 5 0 0计算器计算平曲线上任意点在控制 (或导线 )坐标系下的坐标 ,并在任意点设站应用极坐标法测设平曲线上任意中桩点的放样元素 .
An approach is introduced how to calculate any coordinates with CASIOfx-4500 calculator which arbitrary points on grade curve controls and an idea is suggested that the lofting elements of pile points be surveyed and designed on grade curve by polar coordinates while stations are established.
