邯兖线跨黄河水准测量方法与实践

Methods and Practice in Crossing Yellow River Leveling on the Hanyan Line

在水准测量的路线上,经过较宽的河流、湖泊或峡谷等地貌时会采用跨河水准测量作业方式。跨河水准测量是指为跨越超过一般水准测量视线长度的障碍物而采用特殊方法(倾斜螺旋法、经纬仪倾角法、光学测微法等)进行的水准测量。因此,采用什么样的技术手段和方法进行跨河水准测量仍是一个非常重要的课题。本文以邯兖线跨黄河一等水准测量工作为例,探讨其测量方法与工作技巧,以期为以后跨河水准测量工作的开展提供技术参考。

In the leveling line, sometimes cross the wide rivers, lakes or Canyon inevitably, so the river crossing leveling is a common mode and a common phenomenon in the leveling.River crossing leveling is defined as a barrier across more than ordinary leveling line of sight length and using a special method to level.The methods include incline screw leveling, theodolite tilt angle and optical mi-crometry method etc.Therefore the technical means and methods of river crossing leveling is still a very important topic.The topic dis-cussed the measurement methods and practical work based on the Han Yan line cross the Yellow River a leveling.The aim at provide technical references in river crossing leveling work.
