| 摘 要： | 结合工程实例，对采用真空堆载联合预压法处理大面积沿海滩涂软基的加固效果进行分析和评价。通过表层沉降监测、孔隙水压力监测以及地基施工完成后的十字板剪切试验和浅层平板载荷检测等，得出处理后的软土层沉降量接近1．5m、软土地基物理力学性质变化明显、地基承载力得到大幅提高，表明采用真空堆载联合预压法处理沿海滩涂软基是可行的，具有良好的推广前景。

| Abstract: | Based on construction example, the effect of vacuum stow combining pre-pressure reinforces Shoal Soft Foundation is analyzed and evaluated.Through the monitoring of surface subsidence and pore water pressure, as well as the vane shear test after foundation construction and shallow plate load test, the soft soil after nearly 1.5 m, settlement of soft soil foundation changes obviously, physical and mechanical properties of bearing capacity is vastly improved that adopts vacuum surcharge preloading method of soft foundation treatment coastal beaches is feasible and has good promotion prospects. |
