FBG在预应力混凝土管桩抗拔静载试验中的应用研究
摘要:目前随着地下空间利用的需求越来越大,不少建设项目中抗拔桩的建造费用已经超过了抗压工程桩,甚至达到了抗压桩费用的数倍,合理设计抗拔桩成了设计人员必须注意的大问题。抗拔桩的设计计算在各规范中都没有很明确的规定,设计人员常根据经验和理解进行计算,不同人员的设计结果可能差别很大。采用在预应力混凝土管桩中预埋光纤光栅传感器的方法,通过具体的抗拔静载试验研究预应力混凝土管桩的抗拔性能,为设计提供更合理的抗拔桩设计参数。
Abstract: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.
