Abstract
The invention discloses a measuring method for the cross section of a roadbed in a high mountain region. The measuring method includes the following steps that one point with known plane coordinates and an known elevation is selected on the ground to serve as a control point A, then one point with known coordinates is selected on the ground to serve as an orientation point B, finally, two points are selected on a mountain slope to serve as a measuring point 1 and a measuring point 2; a total station is erected on the control point A, the orientation point B is used for orientation, the coordinate azimuth between the control point A provided with the total station and the orientation point B is calculated, and finally the measuring point 1 is measured in a three-dimensional coordinate mode, numbered and recorded; finally the measuring point 2 is measured. By means of the measuring method, the prism-free total station is used for replacing a common total station and serving as data acquisition equipment, measurement data numbers are directly recorded in a memory of the total station, only one person is needed for operating the total station to complete measurement and recording, measurement staff do not need to climb mountains for measurement, safety of the measurement staff is ensured, and measurement speed is increased.
Description
Technical field
The invention belongs to subgrade cross section field of measuring technique, particularly relate to a kind of alpine region subgrade cross section measuring method.
Background technology
At present, subgrade engineering carried out the measurement of subgrade cross section and the calculating of roadbed earthwork amount to check drawing quantities before construction.Subgrade cross section measuring method generally adopts total powerstation setting-out roadbed king-pile, spirit-leveling instrument and steel ruler is adopted to measure the offset distance of each detail point and king-pile within the scope of roadbed and the discrepancy in elevation or elevation again, this method field operation surveying work amount is large, speed is slow, and precision also affects greatly by taped measurement, taped measurement is from being difficult to guaranteed discharge apart from the normal direction being roadbed king-pile.Also a kind of fast and easy method adopts the transversal section of total station survey roadbed, this method needs an operating instrument, one people founds prism, first with the three-dimensional coordinate of this point of total station survey after vertical prism, use roadbed king-pile and Pian distance that counter program inverse coordinate is corresponding again, measure three-dimensional coordinate again and stored in instrument record with the vertical mirror people of intercom commander to the normal direction of appointment pile No., then go back to indoor and utilize pile No. and offset distance and the corresponding original ground king-pile discrepancy in elevation in the three-dimensional coordinate inverse of instrument record.This method is the most frequently used at present, but the problem that there is not intervisibility needs to remove instrument, cannot to climb the mountain vertical mirror for alpine region and precipitous steep cliff area survey crew.Another is exactly that RTK adds height fitting method fast.There is not intervisibility problem in this method, but the precision of height fitting is by territorial restrictions, in Plain, area, micro-mound adopts surface fitting and the leveling point protecting matching is evenly distributed and makes RTK vertical accuracy can reach mapping base point precision, but larger height anomaly is existed for alpine region, vertical accuracy is difficult to ensure, and vertical accuracy directly affects the accuracy of earthwork, the distance that survey crew is walked is many, and workload is heavy.Alpine region RTK measure there is survey crew equally cannot by precipitous on movement station band and steep cliff is regional measures.Survey crew go up a hill for a moment go down the hill to carry out for a moment roadbed section measure slower than plains region, efficiency is low.
Summary of the invention
The object of the present invention is to provide a kind of alpine region subgrade cross section measuring method, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, present invention employs following technical scheme:
A kind of alpine region subgrade cross section measuring method, comprises the following steps:
1) choose on the ground known planimetric coordinates and elevation a bit as reference mark A, then choose on the ground known coordinate a bit as orientation point B, last hillside is chosen at 2 as measuring point 1 and measuring point 2, and measuring point 1 and reference mark A intervisibility;
2) first total powerstation is set up at reference mark A, directed with orientation point B, calculate the configuration reference mark A of total powerstation and the grid azimuth of orientation point B, finally three-dimensional coordinate measurement is carried out and number record to measuring point 1;
3) finally measuring point 2 is measured, when measuring point 2 and reference mark A intervisibility, direct measurement, when measuring point 2 and the obstructed apparent time of reference mark A, choose on the ground not only with reference mark A intervisibility but also with measuring point 2 intervisibility a bit as intermediate transit point C, the topography and landform character point of reference mark A intervisibility removes total powerstation after measuring directed with A again to C point, all topography and landform character points of measurement intermediate transit point C and other and intermediate transit point C intervisibility.
Preferably, the range of total powerstation is more than 1000m.
Preferably, total powerstation is band automatic rotation motor and the come card TCRP1200+R1000 series Total Station of built-in road Cross Section process of measurement or come card TCA2003 high precision total station or Top health DL-100 series Total Station.
Preferably, total powerstation is Top health DL-100 series Total Station.
Compared with prior art, beneficial effect of the present invention is as follows:
The measuring method that the present invention proposes is measured total powerstation using non-prism and is replaced common total powerstation as data acquisition equipment, measurement data numbering is directly recorded in total powerstation internal memory, as long as second point after first some numbering, thirdly number automatically cumulative 1 without the need to inputting numbering at every turn, as long as a people operates total powerstation and just can complete measurement and record, also climb the mountain without the need to survey crew and measure, guarantee the safety of survey crew, thus improve measuring speed.
Accompanying drawing explanation
Fig. 1 is the process flow diagram of alpine region subgrade cross section measuring method.
Embodiment
Below in conjunction with embodiment, optimal way of the present invention is described in further detail.
As shown in Figure 1, a kind of alpine region subgrade cross section measuring method, comprises the following steps:
1) choose on the ground known planimetric coordinates and elevation a bit as reference mark A, then choose on the ground known coordinate a bit as orientation point B, last hillside is chosen at 2 as measuring point 1 and measuring point 2, and measuring point 1 and reference mark A intervisibility.
2) first total powerstation is set up at reference mark A, total powerstation is Top health DL-100 series Total Station, and the range of total powerstation is more than 1000m, directed with orientation point B, calculate the configuration reference mark A of total powerstation and the grid azimuth of orientation point B, finally three-dimensional coordinate measurement is carried out and number record to measuring point 1.
3) finally measuring point 2 is measured, when measuring point 2 and reference mark A intervisibility, direct measurement, when measuring point 2 and the obstructed apparent time of reference mark A, choose on the ground not only with reference mark A intervisibility but also with measuring point 2 intervisibility a bit as intermediate transit point C, the topography and landform character point of reference mark A intervisibility removes total powerstation after measuring directed with A again to C point, all topography and landform character points of measurement intermediate transit point C and other and intermediate transit point C intervisibility.
