The error propagation theory and Monte Carlo simulations were employed to quantitatively evaluate the robustness of the saturated Turbo FLASH (Fast Low Angle SHot, satTFL) method. The uncertainty and probability density function (PDF) of the satTFL were derived. An out-of-phase method was introduced to correct flip angles larger than 90 degrees. Monte Carlo simulations were implemented to estimate the impact of Gaussian white noises in the image domain and thus the sensitivity could be visualized for different flip angles and signal to noise ratios (SNRs). The uncertainty, Monte Carlo simulations and experiments show that the satTFL is more precise for flip angles around 90 degrees.

Analysis and optimization of the breakthrough accuracy and a proper design of the underground control survey are the most important tasks of the survey engineer in charge of a tunneling project. The breakthrough point P should be treated as two different points P′ and P″ in the accuracy analysis, and the breakthrough error is found from the relative error ellipses calculated for P′ and P″. The accuracy of the underground control surveys (usually open-ended traverses) is much more critical in tunneling surveys than the accuracy of the surface control network. Use of gyrotheodolites decreases the error propagation in underground traverses, particularly when the influence of atmospheric refraction is suspected.

In order to solve the problem of the linear measurement of arch ring for the detection of bridge,a new method is presented that measures the arch ring using a reflectorless total station on the side of the arch bridge and the detail operations are given. Taking account of weakness of edge suveying using a reflectorless total station,some formulas on the 3d coordinates calculation of the above and down edge of the arch ring based on the arch ring points are deduced.According to the law of error propagation, the accuracy of the X and Z axial coordinates are analysed.It is helpful for calculating lateral and vertical deformation and biridges elevation map that the transformation from free-station coordianates to the birdge axis coordinate by programming using EXCEL software is achieved.The method is used for bridges arch ring axial measurement in Qingcheng town,Yuzhong county,Gansu province,and its deformation is consistent with the measured results of the dial indicator,which satisfies the requirement of bridge detecton accuracy.So it is showed that the method is a good way of linear measuring of bridges arch ring.
