【導(dǎo)讀】關(guān)系,以備內(nèi)業(yè)整理時參考,也不必配備記錄計算員。離以及逐樁坐標(biāo)等即可。過這些坐標(biāo)進行平差,使測量精確度更高。了更多的選擇機會,不必為增設(shè)架儀器點而多次讓儀器轉(zhuǎn)站。器操作員1人,后視1人。線設(shè)計可以起到非常大的作用。老路改造,因此測量原則是在滿足規(guī)范要求的前提下盡可能利用老路。海地等路線設(shè)計軟件,通過調(diào)試半徑使得曲線盡可能多地通過這些點。器放后視點,看位置是否一致,這樣可將出錯幾率降至最小。后視點之間的距離不應(yīng)小于架站至測點之間的距離,這樣可以保證測量精度。距誤差、儀器高與棱鏡高量測誤差,而這3種誤差中豎直角觀測誤差的影響最大,中測點的高程值只作參考,而不能用作水準(zhǔn)測量。如在山區(qū)沿溪線的改線測量中,有些路線的幾個中線點上了山頭,如果用水。起誤差過大,造成水準(zhǔn)點之間不閉合。賴全站儀,要結(jié)合以往的花桿皮尺“穿桿”法等。中線組自己用“穿桿法”放的點位。中,創(chuàng)出了一天敷設(shè)10km的速度。
【正文】 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 walkietalkie Midline group to review their use of under law to wear the point release. Another very important point is: Total removal of the time points chosen the best straight Segment on the benefits of such a group is not waiting for equipment to move the center line and layoff points. We use this method in 23 provincial line Nanyang City of Henan Dengzhou Habitat Bangladesh floor to paragraph (plain micro Hill area) the conversion of secondary roads Measurement of the center line, hit a 10 oneday speed of the laying of 10 km. 3 Conclusion Total Station in China in recent years, there is only a matter of universal application of a large area has just begun, but it has brought us convenience is of very significant. In the use of Total Station, will have their own experiences, experience skills, if each user will be able to devote their own experiences, for both of us will be a big asset.
