摘　　要：介绍了一种的钢筋混凝土灌注桩静载荷试验极限承载力的预测法,设单桩的Q-S曲线符合多项式方程,将最小二乘法运用于该方程建立线性方程组,采用高斯消去法编制C语言程序,求出待定系数ai,得到拟合的多项式,用桩顶控制位移代入多项式求出极限荷载。A forecast method for ultimate bearing capacity of reinforced concrete cast-in-place pile with static load experiments is pro posed. A hypothesis of the Q-S curve of single pile is in conformity with multinomial equation, which is applied for the linear equation with the least-square method . The process is written to C programming language with Gauss elimination, the determined coefficients are solved and multinomial equations are obtained. As a result, the ultimate bearing capacity of single pile is the number which is obtained by taking the top control displacement of the pile to multinomial equation.
