Research of Duct Grouting Quality in the Ground Penetrating Radar of Bridge Prestressed Steel Strand
摘要
Abstract
The duct grouting fullness degree of bridge prestressed steel strand are directly related to the safety and use- life of the bridge and the construction technology control and grouting effect testing arise more and more concern. The finite difference time domain method （FDTD） are applied and the generalized completely matched layer （GPML） are adoped as absorbing boundary, two-dismension forword modelling is demonstrated on the common grouting dect defect. Combined with engineering window verification, the characteristics and rules of duct grouting defects of radar image is summarized. The method provides duct grouting fullness degree of ground penetrating radar with evidence.关键词
