| 摘 要： | 对高速铁路路基沉降预测分析的固结度三点法(对数配合法)已在众多工程实践中得到应用并取得了较为理想的效果,但方法仍存在缺陷,使其在工程应用中有一定的局限性。利用序列二次规划法(SQPM算法)对传统的三点法进行改进并结合工程实例进行了应用探索,结果表明,改进后的固结度三点法对原始数据初值的选取精度要求较低,扩大了它的应用范围。

| Abstract: | Three-point method calculating consolidation degree(logarithmic matching method) for predicting high-speed railway subgrade settlement has been applied in many engineering practices and has achieved the desired result,but the method still has defects,so its application has some limitations in engineering.The traditional three-point method has been improved using sequential quadratic programming(SQPM algorithm) and its application has been explored combined with engineering practice.It is shown that the impr... |
