Study on Anti-Pulling Static Load Test of Prestressed Concrete Pipe Pile Using Fiber Bragg Grating Technology

Currently, the demand of developing the underground space is becoming larger and larger. The construction costs of uplift pile has become more than compression pile in some projects, even more than number times. The pile designers must pay more attention to the reasonable design of uplift piles. The design calculation of uplift piles is not very clear in specification. The pile designers always calculate with their experience and understanding, the different designers have different design results. This article referred to the method that used fiber bragg grating senor embedded in the prestressed concrete pipe pile to monitor the stress of pile. Combining a certain anti-pulling static load test of prestressed concrete pipe pile, the properties of prestressed concrete pipe pile had researched, it can provide more reasonable parameters to the design of uplift pile.
