摘要
几何水准测量是一种精密的测量方法,但利用传统的光学水准仪测量作业则效率较低,不能很好的满足国民经济飞速发展中各种大型工程建设的需要。电子水准仪的出现,使水准测量实现了自动化、数字化,是水准测量仪器发展史上的一次技术革命。作者结合长期工程实践,提出了一种新观点,即电子水准仪水准测量时无需变动仪器高,其结果仍能满足工程施工测量精度的需要,既缩短了工期,又降低了施测成本,具有较好的经济效益。
Geometric leveling is an accurate surveying method but it cannot afford to resolve the large-scale engineering problems due to its inefficiency in high-speed national economic development.It thanks to invent the electron leveling that leveling surveying realized digitalization and automation, which is a technological revolution in leveling surveying instrument history. Combining the surveying engineering practice,the paper refers a new conception that it is not use to alter the instrument height while leveling. With no altering the height,it can cut down the observation time for a project and reduce surveying cost. Under prerequisite to surveying precision,an obvious economic efficiency is acquired.
