In recent years, with the great development of traffic construction, tunnel engineering passes through weak stratums and high stress sections with bad addresses are increased, various phenomena of collapse, water burst, bottom heave and large deformation often occur, the bottom heave is one of the phenomena, once the deformation is continuously uncertain, great hidden dangers are left for engineering construction and later-stage operation.
When inverted arch heaving occurs in the tunnel/tunnel, it is typically a post-mortem remedy; if the monitoring of the bad geological section is not in place, the tunnel floor after the second lining is cracked, and the tunnel floor has to be disassembled and replaced; in operation, the inverted arch bottom drum is serious, and the speed has to be reduced.

Secondly, each party has insufficient importance; the tunnel inverted arch bottom bulge causes consequences, few cases exist on low-speed railways and in past, all parties consider the necessity not to be large, and the cost is not worth. Thirdly, the monitoring means is unscientific; for example, if a leveling instrument is adopted for manual monitoring, at least 4 persons are needed for monitoring personnel, and the monitoring points are easily damaged due to being buried on the floor; if automatic monitoring is adopted, the most applicable static level can not measure horizontal displacement due to the fact that the measuring range and the precision can not be obtained at the same time, and the construction process is complex in installation, easy to cause damage, high in maintenance difficulty, low in manufacturer enthusiasm and low in power.
The tunnel inverted arch bottom heave can bring serious influence, and a train running at high speed jolts and even derails; for example, in an illumination tunnel and a post service tunnel of a certain line in operation, due to the fact that the inverted arch is bulged at the bottom, the speed of a high-speed rail has to be reduced; in the construction process, a tunnel of a noble wire has to be rebuilt due to large deformation, and a ballastless track is changed into a ballasted track.
