摘要
自 Terzaghi's 固结理论问世以来,软土地基沉降计算方法层出不穷,如经验公式法、有限元法以及神经网络方法等,每一种方法都有其适用性。因此,应根据工程实际情况选择合适的方法。笔者分析了传统计算软土路基沉降的方法,并指出了其弊端,提出了用神经网络和有限元进行结合计算软土路堤沉降的方法。
The principle and calculation methods for analyzing settlement of soft clay subgrade appear frequently since Terzahi's consol- idation theory was published.There are many methods,such as semi-empirical formula,graphical methods,numerical analysis and ANN method.The author considers that every method has its actual effect,so the engineer has to choose a calculation method according to ac- tual engineering need.The disadvantages the traditional methods in calculating the subgrade settlement are dicussed;and suggests a new method integrated by ANN and numerical analysis to calculate the settlement is suggested.
