Instrument is spirit level or theodolite, then the method for adjustment of the height of tripod base includes in S4：
S411, disposes spirit level or theodolite in central point, scale, and the perpendicular disk reading of theodolite is erect on the datum mark
For (90 ° of+i) or (270 ° of-i), wherein, i is index error of vertical circle；
S412, spirit level or theodolite are successively read the reading of scale described in four, and l is designated as respectivelya、lb、lc、ld；
S413, judges whether the reading of scale meets the first formula：
la+lb=lc+ld；
If being unsatisfactory for the first formula, repeatedly datum mark described in S3 step measure setup four；
If meeting the first formula, judge whether measurement result meets the second formula：
la=lb=lc=ld；
If being unsatisfactory for the second formula, the height of foot screw of the tripod base of the spirit level or theodolite is adjusted to meeting the
Two formula.
7. a kind of measuring method for setting up dynamic benchmark plane as claimed in claim 1, it is characterised in that：If the measurement in S4
Instrument is total powerstation, then the method for adjustment of the height of tripod base includes in S4：
S421, L is designated as setting up prism described in four on datum mark and measuring prism height respectivelya、Lb、Lc、Ld；

S is not designated as ita、Sb、Sc、Sd, vertical angle is designated as ɑ respectivelya、ɑb、ɑc、ɑdH is designated as respectively with the discrepancy in elevationa、Hb、Hc、Hd；
S423, judges whether measured value meets the 3rd formula：
(La-Satanαa)+(Lb-Sbtanαb)=(Lc-Sctanαc)+(Ld-Sdtanαd)
If being unsatisfactory for the 3rd formula, repeatedly datum mark described in S3 step measure setup four；
If meeting the 3rd formula, judge whether measurement result meets the 4th formula：
La-Satanαa=Lb-Sbtanαb=Lc-Sctanαc=Ld-Sdtanαd；
If being unsatisfactory for the 4th formula, the height of the foot screw of the tripod base of the total powerstation is adjusted, to the 4th formula of satisfaction.
