| Abstract: | The formular for estimating accuracy of tunnel breaking-through survey in branch tunnel is derived in detail. This formular considers the influence caused not only by the angular accuracy and the distance one on this kind of survey, but also that caused by the accuracy of control point outside the tunnel. The formular is derived rigorously. Finally, some conclusions are obtained |
