An institute is obtained at interval of preset time it should be noted that obtaining at least two first height values and can be
The first height value is stated, which can be determined according to the actual situation, such as the interval preset time can be half
The moon, one month, three months, half a year, 1 year etc.；The preset time can be determined according to the soil layer situation where bridge.Base
Correcting the first elevation difference at least two first height values can be for based at least two first height value
Changing value correct the first elevation difference, be datum mark relative to the standard basis mainly due to the first height value
The elevation of point, and the datum mark is located at the position that easily deformation occurs；If obtained described in one before being spaced preset time
First height value regains first height value after being spaced preset time, then obtained before the preset time of interval
There may be variations for first height value obtained after first height value and interval preset time, therefore, can be based on
The changing value of at least two first height values corrects the first elevation difference, to ensure the first elevation difference just
True property.In order to facilitate understanding, illustrate here, it is assumed that at interval of preset time be one month, for the first time obtain the first elevation
Value is 100mm, and interval obtains the first height value for the second time after one month be 99mm, and the first elevation difference is 2mm, then can be with base
The changing value 1mm amendment first of second of the first height value of acquisition is high after obtaining the first height value in first time and being spaced one month
First elevation difference 2mm specifically can be changed to 1mm by path difference value 2mm.
Based on described in the determination of first height value, the revised first elevation difference and the second elevation difference
The elevation of multiple observation points can be to determine institute based on first height value and the revised first elevation difference in real time
The elevation of datum mark is stated, then the observation point is determined based on the elevation of the datum mark and the second elevation difference
Elevation.As an example, the revised first elevation difference that can be added deduct based on first height value is real-time
Obtain the height value of the datum mark, then the height value based on the datum mark adds deduct the second elevation difference
Determine the elevation of the multiple observation point.Wherein, " adding " operation is the case where becoming arch deformation for shape, and " subtracting " operation is needle
The case where sedimentation and deformation is become to shape.

Such as, at least two observation points differ 1m in height.Pre-determined distance condition can be spaced centainly between at least two observation points
Distance on, for convenience understand, here for example, for example, the distance at least two observation point intervals be 1m.
In order to facilitate understanding, be illustrated here in conjunction with Fig. 2, in Fig. 2, due to the corresponding Bridge Pier of observation point n3 with
There are route longitudinal slope between the corresponding Bridge Pier of observation point n5, which refers to same slope section point-to-point transmission on route vertical section
Height difference and the ratio between its horizontal distance, understand for convenience, it is assumed here that the height difference of same slope section point-to-point transmission on route vertical section
For 1m, the position that the corresponding Bridge Pier of observation point n5 is located at can the position that is located at of Bridge Pier more corresponding than observation point n3 it is low
1m, so that the low 1m in top surface of the top surface Bridge Pier more corresponding than observation point n3 of the corresponding Bridge Pier of observation point n5, for side
Just it measures, needs Bridge Pier height difference in continuous observation o'clock in about 1000 meters of 1 meter or so or distribution distance as one
Observe section.Observation point n1, observation point n3 and the corresponding Bridge Pier of observation point n5 can be set to an observation in Fig. 2
