Aiming at the seawall safety problems in the context of global climate change,sea level rise and the white-hot advance of large-scale reclamation projects,a review research on the status of seawall monitoring in China is carried out.Using the innovative research methods of big data analysis and based on the China Journal Full-text Database CNKI,the current situation of seawall monitoring in China is analyzed from four aspects,i.e.seawall detection and monitoring theories,seawall safety detection,long-term monitoring of seawall safety and typical cases of seawall monitoring.The results are as follows.Most of the existing seawall monitoring are focused on the monitoring of the construction period,and the research on the hidden dangers of the old seawall is not comprehensive and thorough.Two branches of osmotic pressure and sedimentation theory in the theory of seawall monitoring are summarized,and it is pointed out that neither of them has mentioned the influence of waves on the seawall,and suggested that the wave data should be incorporated into the influencing factors such as osmotic pressure and settlement of seawall.It is pointed out that although people have a certain understanding of all kinds of detection methods,and suggested to put forward a set of standardized integrated methods for detecting hidden dangers of seawalls.It is suggested that the study of long-term monitoring of seawall safety is still in the preliminary stage,and the monitoring data of marine deformation monitoring and marine hydrological monitoring data should be synchronized and integrated to predict the safety of seawall in real time.
