It is necessary to carry out the principle of constant measurement and correction during the sinking process of caisson shaft,especially to carry out information monitoring during the whole sinking process,so as to achieve uniform and safe sinking.Through taking the sinking process monitoring technology of a certain caisson as an example,the study discusses the evolution characteristics of various parameters,such as sinking rate and dip angle,etc.It is found that the sinking rate of the caisson is basically uniform,and the displacement and inclination degree meet the construction specifications and safety requirements.Through considering the influence of soil frequency and resistance,a kind of damping oscillation attenuation evolution characteristics is presented in each stage of sinking of caisson.This feature can be used to feedback the technical control of the whole construction process or evaluate the quality control of the whole construction process,which has guiding significance for the construction of similar projects.
