【摘要】 给出了钻孔灌注桩水下砼灌注所采用的数学模型，根据此数学模型计算了初灌量，并把后续灌注分为５个阶段，对５个阶段的有关多数进行了近似计算。将计算值与工程实例进行了对比，基本吻合。更多还原

【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 .更多还原
