摘要
随着社会经济的大力发展,交通设施也不断的完善,对公路的需求也越来越大,近几年,我国大力修建公路,而公路施工放样在公路建设中至关重要。而在公路施工放样过程中经常会碰到一些通视条件与精度问题,从而影响工程进度。本文介绍了在公路施工中,偏角法放样在处理一些视线障碍问题时的可取之处,全站仪极坐标放样法在匝道中线定位中的应用以及对其进行精度分析。
As the society economy vigorously develops and the traffic facility continuously complicates, road demand becomes more and more important. During these years, our country have constructed a lot roads, highway construction lofting is very important and high effect in highway construction, therefore, highway lofting plays an important role in it. The intervisbility condition and the precision is the usual problem in highway construction. This article introduced the strong suit of the entire station meter method in highway construction lofting characteristic as well as the method of deflection angles when deal with some special lofting issue. We have carried on the theory precision analysis as well as the application to the total station meter opposite side survey lofting function, the total station meter polar coordinate lofting law as well as carries on the precision analysis in the circular route median localization application to it.
