| 摘 要： | 利用最小二乘原理把固结系数确定问题转化为非线性优化问题,再用单纯形法对固结试验数据进行拟合计算,直接求出固结系数。计算结果表明:单纯形法可消除常规作图法中人为因素影响,有效地减少误差;且方法收敛速度较快,计算精度较高,通用、可靠。 |

| Abstract: | Based on the least square principle,the coefficient of consolidation evaluation is a non-linear optimization problem with formula transformation,and simplex method for evaluating coefficient of consolidation by automatic fitting calculations with data from consolidation test is proposed.The results show that the simplex method can eliminate the man-made factors during graphical construction.Moreover,the method is a universal and reliable method with rapid convergence and high precision. |
| Keywords: | coefficient of consolidation simplex method least square principle |
