摘　　要：该工程场地有深厚的软土层,为减小工后沉降,现通过堆载预压的方式处理地基。结合该工程实例,通过数值计算软件Settle3D对该工程进行模拟,结果表明:Settle3D能较好地模拟场地分级加载的情况;考虑到模拟沉降与实测沉降有一定差异,通过土体参数反演优化模型计算结果,发现后期沉降的预测精度得到明显提高。The project site have deep soft soil layers.In order to reduce post-construction settlement,the foundation is treated by the preloading method.Combined with this project example,the project is simulated by numerical software settle3D.The results show that settle3D can better simulate the site's graded loading situation;and considering that there is a difference between simulated settlement and measured settlement,the soil parameters are inversed to optimize the model simulations.It is found that the prediction accuracy of late settlement is significantly improved.
