摘　　要：在用流变模型对地基沉降进行计算时发现,当地基土为土岩组合体时,利用Burgers流变模型方程计算出的沉降与实测沉降值有一定差距。因此提出一种基于Hooke体的新型元件,对Burgers流变模型进行修正。修正后的流变模型方程计算的沉降值与实测值吻合度较高,并利用修正模型对镇江市堆山工程的地基沉降进行了预测。提出的新型流变元件具有一定的实用价值,可为类似的工程提供参考。A new theological component based on Hooke body is introduced in this paper. Using rheological model to calculate the settlement of the foundation, the calculated and measured values are different when foundation is composed of soil and rock. Therefore the new theological component called HN body is created. The settlement calculation model based on improved rheologieal model is used to calculate the foundation settlement, the results are quite same to measured values. Finally, the new settlement calculation model is used to predict the settlement to provide guidance for future monitoring work, and it provides reference for similar projects.
