| 摘 要： | 在隧道施工断面测量过程中，在最小投入的前提下，采用极坐标法能够及时为施工提供可靠的测量数据，准确地指导断面施工。而三维坐标段落法，只需测量任意点的三维坐标即可计算其偏差，全面地反映整个段落任意桩号各个点的超欠挖情况。

| Abstract: | Cross-section measurement in the tunnel construction process,under the minimum investment used the polar coordinates method for the construction could provide reliable data and accuracy to guide the construction But three section-dimensional coordinates paragraph method just measures the three-dimensional coordinates of any point that could calculate the deviation,then it could comprehensively reflect the need to dig where between the different point. |
