摘要
针对目前常规水准测量在山区公路高程控制测量中的局限性,本文提出了一种三角高程与常规水准测量相结合的混合构网方法,并通过实例得出,这种方法充分利用了两者的优势,在保证成果的可靠性和精度的同时,大大提高了工作效率,缩短了生产周期。
For the limitations of spirit leveling in the mountain highway vertical control surveying, a method of mixed network which includes spirit leveling and Trigonometric leveling is proposed. After using this method on project, the result shows that by using the advantages of the both, this method greatly improves the efficiency and reduces the production cycle while ensuring the reliability and the accuracy.
