关于山区高速公路控制测量网建立方法的探究

Research on the Establishment Method of Highway Control Measurement Network in Mountainous Area

高速公路建设投资大、建设周期长,特别是在地形起伏变化较大的山区,需要借助控制测量网进行详细的勘测设计。但是,在山区高速公路控制测量网构建时,往往面临着高等级的平面以及高程控制点分布不均匀无法满足设计要求的问题。在现实操作中,因地形复杂多变,应做到具体问题具体分析。高程测量作为高速公路控制测量网构建的核心环节,可以联合测量高等级控制点以建立逐级的平面控制测量网和高程测量网,从而达到高速公路规范设计标准要求,基于此,对控制测量网的建立方法进行了探究。

Especially in mountainou areas with great topographic changes,the construction of expressways requires large investment and long construction period,which requires detailed survey and design with the help of control measurement network.However,in the construction of mountain highway control network,it is often faced with the problem that the distribution of high-level plane and elevation control points is not uniform,which cannot meet the design requirements.In practical operation,due to the complex and changeable terrain,specific problems should be analyzed.As the core part of the construction of highway control measurement network,elevation measurement can be combined with the joint measurement of high-level control points to establish step-by-step horizontal control measurement network and elevation measurement network,so as to meet the requirements of highway code design standards.Based on this,this paper explores the establishment method of control measurement network.
