A
Described the 6th step is derived after sedimentation B ＇ with respect to the difference in height h of A ＇ by inclinometer 9 reflection data
A-B
The B point is with respect to the sedimentation value Δ of this backfill layer
BDesign formulas as follows:
Δ
B=Δ
A+?h
A-B。
Because the deadweight of inclinometer 9 is smaller, therefore very little with respect to the displacement of total sedimentation pipe 6 by the caused vertical displacement of its self gravitation, so inclinometer 9 can be ignored because of the caused vertical displacement of self gravitation.
