采用变空间步长的有限差分法 ,求解了多层地基考虑施工期加荷过程的一维固结问题。运用所编程序分析了固结度与时间因子关系、固结沉降动态变化趋势。为实际工程中固结沉降的求解提供了有价值的计算手段。 The finite difference method with variable space step is used to solve the one-dimensional consolidation problem of multi-layer foundation considering loading process during construction. The relationship between the degree of consolidation and the time factor was analyzed by using the programmed program, and the trend of consolidation settlement dynamic change was analyzed. It provides a valuable calculation method for the settlement of settlement in practical engineering.
