Description

technical field [0001] The invention relates to the technical field of tunnel engineering measurement, in particular to a displacement detection system and method for tunnel space deformation. Background technique [0002] Existing tunnels have had their original shape since they were built (e.g. Figure 5 As shown), with the changes of the surrounding soil and itself, its various parts may be deformed, and the deformation may occur in any direction. But its two ends (ie Figure 5 A, B points shown) are usually considered as fixed points. [0003] With the vigorous development of underground transportation in our country, there are many displacement monitoring methods for the interior and surface of subway tunnels at home and abroad, mainly including settlement observation and horizontal displacement observation. Settlement observation refers to laying out a series of reference observation points in the target deformation area, and using a level instrument for leveling meas...
