水准测量作为常用且精度较高的方法在现代测绘中发挥着不可代替的作用,但在具体的实施过程中,因多种因素的制约,系统误差和偶然误差总是伴随同时产生,不可避免。文中结合实践,针对存在的误差现象及产生原因进行简要分析,具体从四个方面提出控制方法,以期最大限度地将测量误差减小至可以忽略的程度,确保工程精度和工程质量。 Level measurement, as a common and accurate method, plays an irreplaceable role in modern surveying and mapping. However, due to a variety of factors, systematic errors and accidental errors always occur together and are inevitable in the concrete implementation. According to the practice, this paper analyzes the existing error phenomenon and its causes, and presents the control methods from four aspects in order to minimize the measurement error to a negligible extent and ensure the engineering accuracy and project quality.
