| 摘 要： | 针对地下工程导线测量中,采用测角量边的单一导线控制测量而导致控制精度较低的问题,分析了直伸型导线测量中加测陀螺方位角的数量及其增益,并探讨了直伸型导线和非直伸型典型导线,如L,Z,U型导线加测陀螺方位角的最佳位置。

| Abstract: | In guide line survey of underground project,the single guide line of surveying the angle and the border length is adopted to control surveying,such a method may lead to a lower controlling precision.Aimed at this problem,the numbers and its benefit increments of adding to survey the top-shaped azimuth angle in linear and extending shaped guide line survey are analyzed in this paper,and the linear and extending shaped guide line and some other types of guide line,such as L,Z and U-shaped guide line,are studied.Furthmore,the optimum places of adding to survey the top-shaped azimuth angle in L,Z and U-shaped guide line are also discussed in this paper. |
