The shield tunnel has the advantages of high construction speed, high automation degree, small influence on surrounding environment and the like, and is widely applied to urban tunnel construction. The shield tunnel lining is contacted with the outside soil body through grouting liquid, and the pressure fluctuation of the outside soil body has direct influence on the safety of the tunnel lining and the waterproof of a tunnel joint, so that the monitoring of the soil pressure outside the tunnel for a long time, accurately and conveniently has a vital effect on the safety and the durability of the tunnel.
The existing method for monitoring the soil pressure outside the shield tunnel mainly adopts a traditional soil pressure box pressure measurement method, the method is characterized in that a soil pressure box is buried outside a segment lining in advance, and an outer membrane of the soil pressure box is kept parallel to the outside of the lining, but the method has more problems, and the main problems are as follows:

2. The lead hole of the soil pressure box weakens the bearing capacity of the segment
The soil pressure box lead wire needs to be led out through the inside perforation of the segment, and the lead wire hole reduces the structural integrity of the segment, causes segment damage, leads to the structural strength reduction of the segment lining, and weakens the segment bearing capacity.
3. The lead hole of the soil pressure box is easy to cause water leakage
The soil pressure box lead wire is perforated through the duct piece, so that the sealing performance of the duct piece is also damaged while the integrity of the duct piece is reduced, the contact between the rubber protective layer of the lead wire and the duct piece is not tight, the water leakage phenomenon is easy to occur, and the durability and the applicability of the duct piece lining are reduced.
4. Inaccurate measurement results
The soil pressure box is pre-buried in the duct piece outside, after grouting behind the wall, is wrapped up by the grouting liquid, can't direct contact outside soil body, and the sensitivity of soil pressure box declines thereupon, leads to measuring result inaccuracy.
The existing method for measuring the soil pressure by using the film is insensitive to the soil pressure detection and low in measurement accuracy due to the thick film material, and the film has high price, and the film with the size of 1 square meter reaches 28 ten thousand yuan, so that the economical efficiency is poor.
