| 摘 要： | 结合沪宁高速公路扩建工程实际情况，对在导线复测中出现的起算导线点数量较少且不能通视，导致导线无法获得起算边（无连接角）的计算问题进行研究，提出解决办法，并通过工程实际运用验证该方法的可行性。

| Abstract: | In combination with the practical situations of Shanghai--Nanjing Expressway Expansion Project, this paper investigates the computation problems since the traverse cannot acquire the initial side （without connecting angle） due to fewer initial traverse points appearing in repetition measurement and without intervisibility and puts forward the solutions. It also verifies the feasibility of this method via the practical application in projects. |

| Keywords: | Shanghai--Nanjing Expressway expansion repetition measurement of traverse compensating computation without connecting angle |
