摘要
地质工程测量是地质勘查中极为重要的基础性工作。因此,选用合理而科学的测量方法则显得尤为重要。结合特殊的地质条件,将似大地水准面精化成果用于高程系统的起算面,整个计算过程具有高精度、三维性、动态性、多功能等特点。显然将其运用在地质工程测量中获得其高程成果有可靠的可行性。该方法不仅能保证测量结果的精度要求,而且可以减少一定程度的工作量,从而降低测量成本提高经济效益,同时测量的效率也得到了提升。
Geological engineering survey is a very important basic work in geological exploration.Therefore,it is particularly important to choose a reasonable and scientific measurement method.Combined with special geological conditions,the results of quasi-geoid determination are used as the starting surface of height system.The whole calculation process is characterized by high precision,three-dimension,dynamic and multifunction.Obviously,it is reliable to use this method in geological engineering survey to obtain its height results.It not only ensures the accuracy of the measurement results,but also reduces the workload to a certain extent,thereby reducing the cost of measurement and improving economic benefits and the efficiency of measurement.
