摘　　要：地下人防坑道积水,不利于三维激光扫描技术的应用,只能利用全站仪数字测图的传统作业方式。老旧坑道空间狭窄、湿度高,不同地段温差大,全站仪测量精度受到影响,当积水无法抽干时,设点困难。文中以某人防坑道测量项目为例,针对各种不利测量条件,阐述了切实可行的解放方法、方案。Three-Dimensional laser scanning technology was also limited cause of hydrops in civil air defense tunnel, only traditional digital topographic surveying by total station could be used. Age-old civil air defense tunnel had the characteristics of narrow space, high humidity, and temperature difference was large in different areas. The accuracy of instruments was affected. When the accumulated water in the tunnel could not be pumped out thoroughly, it was not able to set up normal control point, which brought great difficulties to topographic survey. In the paper, taking a certain civil air defense tunnel surveying project in Hainan province as an example, the feasible liberation methods and schemes were expounded in practical operation, aiming at the unfavorable survey conditions above.
