Abstract: Researches on mechanical property of inland river overhead vertical wharf are mainly based on the numerical analysis, model experiment and field test. With the rapid development of science and technology, the disadvantages of traditional strain test technology increasingly prominent. In order to obtain the strain field, the displacement field and the relationship between ｌｏａｄ and deformation of wharf structure more conveniently and reasonably, this paper presents two new detection methods, including the high speed camera imaging technology based on digital speckle (DSCM) and the pressure sensitive paint technology (PSP).The application of these two methods can quickly and accurately get the work mechanism and the energy distribution of structure, providing the reference for the optimal layout design of wharf structure to make more actual judgment.
