摘　　要：探讨了山区高速公路场景控制网构建关键制约因素,提出了一套控制测量技术方案。以四川省西部山区某高速公路为例,顾及现场环境、气候特征,从平面控制测量、高程控制测量和注意事项等角度阐述了潜在的问题与解决措施,合理组织工序,解决了控制点投影变形误差大、高程精度低等问题。该方案针对性强,参考价值高,可快速在类似工程场景下复用。We discussed key constraints on the construction of control networks for mountainous highway scenes,and proposed a set of control survey technology solutions.Taking a mountainous highway in western Sichuan Province for example,we elaborated potential problems and solutions from the perspectives of planimetric control survey,elevation control survey and precautions.Taking into account the site environment and climatic characteristics,we reasonably organized the process to solve problems such as large projection deformation errors of control points and poor elevation accuracy.The solution is highly relevant,has high reference value and can be quickly reused in similar engineering scenarios.
