| 中文摘要:通过在大面积堆载场地设置地表沉降监测仪器，进行历时3年的现场监测，对大面积堆载作用下滨海吹填软土地基的沉降变形特性进行了分析研究，揭示了大面积堆载作用下软土地基变形特性不同于常规荷载作用下软土地基变形特性的规律，总结了大面积堆载条件下软土地基变形沉降的规律，利用数值计算方法模拟了地基沉降变形规律，分析了地基破坏模式，数值计算结果与现场监测结果有着较好的一致性，在400 kPa堆载力的作用下，最大沉降值约为1.6 m。 |

| Abstract:By setting surface subsidence monitoring instruments in a large area of the loading site, the on-site monitoring lasted 3 years, and the analysis was made on the deformation characteristics of coastal hydraulic fills soft ground subsidence under large area heaped load. It is revealed that the deformation characteristics of soft ground under large heaped load are different from those under normal load and the soft ground deformation settlement law of large area heaped load conditions is summarized. By the use of numerical methods, the foundation deformation law is simulated and the foundation failure mode is analyzed, the numerical calculation results and the field monitoring results have a good coherence. Under 400kPa heaped load force, the maximum settlement value is approximately 1.6m. |
