There are many cases of sand throwing on seawall in reclamation projects,and the safety and stability of seawall under construction directly relates to the construction control level.But up to present,there is no research on the safety control method of sand throwing yet,and the construction mostly relies on the experience,thus the construction faces great safety risks during implementation. Combining with the actual need of Shantou east coast park,we propose a complete set of safety control method for sand throwing on the seawall under construction from the seawall stability computation,construction safety monitoring technology and construction organizational measures,which achieved good effects in the engineering application,and guaranteed the seawalls’ safety.
