【摘要】 单桩载荷试验的Q-S曲线符合抛物线方程,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a、b、c,得到拟合的抛物线,用抛物线中的顶点求出单桩竖向极限承载力。工程实例表明该方法可行。更多还原

【Abstract】 The Q-S curve of static load test for a single pile is in conformity with the parabolic equation,which is applied to the linear equation with the least square method.The process is written to C programming language with Gauss elimination,then the undetermined coefficients a,b and c are solved and the fitted parabolic equations are got.As a result,the vertical bearing capacity of the single pile is extracted by the apex of the parabolic curve.The practical cases indicate that the method is reasonable.更多还原
