FBG传感器在PHC管桩水平载荷试验中的应用
Application of FBG Sensing Technology in Lateral Load Tests on PHC Pipe Piles
摘要
Abstract
The advantage of the FBG sensor was introduced and the FBG sensors installa-tion process in PHC pipe piles was also proposed. Combined with practical engineering,ac-cording to the monitoring results of PHC pipe pile lateral static load tests horizontal,PHC pipe pile body force and deformation was analysed after data processing:On the ground, pile bending moment was closed to zero. With the increase of depth, bending showed a trend of decrease after the first increase,and the maximum was (1/12~1/6) pile under the ground. The bending deformation was mainly distributed in the pile length above 1/3 pile,and almost no deformation in the pile body below 1/3 pile;the deflection of the pile body decreases with increasing depth,and it was ultimately closed to zero;the horizontal load has significant impact on deflection of the pile body. Through comparing the experi-mental data with the theoretical calculation result,the testing data from the FBG sensor is reliable and could be better applied to the PHC pile lateral static load test.关键词
