道路交点设站测定中桩方法

Measuring methods of middle stakes in crossing points of highway

本文介绍了施工放样过程中.在交点安置仪器测定曲线中桩点位的方法。给出了计算公式、测定步骤及计算实例。特别对高等级公路的施工定线.即能提高放样精度。又能加快放样的速度.是只得推广应用的有效方法。

The method of measuring middle stakes in crossing points of roads during construction is presented in this paper. The authors deduce the calculating formula and present the used steps of this formula. By examples, this formula is a feasible. To alignment of advanced roads, this method can both improve the sampling precision and quicken the sampling.
