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。
When using the rheological model to calculate the foundation settlement, it is found that there is a certain gap between the settlement calculated by the Burgers rheological model and the measured settlement when the local foundation soil is a combination of soil and rock. Therefore, a new element based on Hooke body is proposed to modify the Burgers rheological model. The modified rheological model equation shows that the settlement value is in good agreement with the measured value, and the ground settlement of the pile-hill project in Zhenjiang City is predicted by the modified model. The proposed new rheological element has some practical value, which can provide reference for similar projects.
