【正文】 re more buildings, and sometimes moving equipment will take a 12 point move is often no longer the other stations, But with the mobile reference point and reference point for measuring a bination of methods, each has made to save time, effort, and the results meet the accuracy requirements. Total Measurement Application of functional skills Although the level of total station measurements cumbersome procedures, and accuracy is not high, but sometimes the function of height can be measured effectively. As in Mountain edge streamlet line measurement of change, some routes in several midline point on the mountain, if measured by leveling to the elevation of these points, based on past experience, Level turn to the hilltop after two previous instrume nts Easily lead to error is too large, resulting in closure between the standard points. Our approach is: in the mountains at the foot of the election of a fixed reference point for parison, With total station read out the points of Zaxis height, and then release with Total Station in the midline point of these hills, when they point the way to measure the Zaxis height can be calculated in relation to these points, the reference point the foot of the hill .The 2021 級土木工程專業(yè)英語科技 文獻(xiàn)翻譯 9 elevation, so that measured by leveling the height of the reference point, coupled with the height difference between them, they will have the hills on the center line of the elevation points. This the benefit is: does not affect the measurement accuracy has been the high point of the mountain at the same time, the way to avoid leveling easily lead to the standard of the hill between the occurrence of nonclosure. Total Station with other measurement methods used in conjunction Measuring Total Station can be centerline to improve the measurement speed, but because of its own measurement of the use of the mechanism of making it have some limitations, such as the barrier, when, as often required when moving points, in particular Measurement in the plains, as station equipment to move a lot of ti me to delay, the impact of the measurements. In fact, the process of laying the center line does not necessarily have to rely too much on total station, in conjunction with the previous tape under a flower, wear bar Law. We microhill in the plains areas, especially in areas with more line segments, the method of measuring the center line is: only used to take control of Total Station Point, that is, line segments, one for every 300 m center line, the curve point above the center line of the release by the Total Station, straight from the points A, B 2 personal expertise lay in front of the middle group, after the laying of A continue to the front 300 m down a center line point B to stay under to take a flower behind the center line group when the Front View, from the center line group using binoculars, measuring tape, flower clubs, walkietalkies and other tools to wear bar, which line group to the The full Miriam released the centerline station point for review by 2:00 after passing in front of 300 m A Department Total points also to the well, B to A, as the Department before the legislature, A continues to move forward, it can be the middle of Total Station through the wal
