Abstract:A mathematical model used in under-water concrete injection of bored piles is proposed, according to which,the initial injection amount is calculated, the supplement injection is divided into five stages, and appoxi-mate calculation is made on the parameters relevant to the five stages,the calculation values are compared with those obtained from field construction cases and found to coincide with each other in general .
