摘要
针对圆弧段放线过程中由于地形地物限制而遇到的种种困难,介绍了直线拉线法,坐标放样法结合坐标计算法、经纬仪测角法、方位角法四种应用广泛的圆弧形平面施工放样方法,以确保航道整治工程中的驳岸线形、外观。
According to the difficulties encountered in line laying process of are segment caused by landform and ground objects four line laying methods in plane construction of arc： straight line positioning method, coordinate staking out method combined with coordinating calculation method, transit angle measurement method and azimuth method are introduced, in order to ensure the line shape and appearance quality of waterfront in waterway improvement work.
