【摘要】:在高速鐵路、高速公路等工程項目中為限制長度變形,對坐標系的選擇提出了更高的要求,有時須建立抵償坐標系。通過對橢球膨脹法建立的抵償坐標系與普通坐標系進行實驗數(shù)據(jù)驗證,發(fā)現(xiàn)抵償坐標系得到的變形值更小,精確度更高,但面臨計算量大、易出錯等問題的困擾;贛ATLAB平臺的抵償坐標的實現(xiàn),不僅能夠對數(shù)據(jù)進行批量化處理,還具有速度快、精度高的優(yōu)勢。
[Abstract]:In order to limit the deformation of length in high speed railway, highway and other engineering projects, a higher requirement is put forward for the selection of coordinate system, sometimes the compensatory coordinate system must be established. Based on the experimental data of the compensation coordinate system established by the ellipsoidal expansion method and the ordinary coordinate system, it is found that the deformation value of the compensation coordinate system is smaller and the accuracy is higher, but it is beset by the problems of large amount of calculation and easy to make mistakes. The realization of compensation coordinates based on MATLAB platform can not only deal with the data in batches, but also have the advantages of high speed and high precision.
