| 摘 要： | 应用高真空击密法对宁波镇海地区软土地基处理进行了施工工艺试验研究。通过对高真空击密法地基处理过程中的地面沉降和超孔隙水压力等进行跟踪监测，研究了不同排水与击密参数时地基沉降和超孔隙水压力消散规律，并且对比分析了处理前后土体物理力学性质的变化。试验研究表明，高真空击密法处理后土体强度有了明显提高，试验达到了预期目的．证明高真空击密法处理该类型软土地基是可行的。

| Abstract: | An experimental research was carried out on the construction technology of soft soil treatment in Zhenhai area of Ningbo by High Vacuum Densification Method(HDVM).Through monitoring ground settlement and dissipation of excess pore-water pressure,we studied the variation law of ground settlement and dissipation of excess pore-water pressure in different drainage and densification conditions,and analyzed the variation of physical and mechanical properties of soil before and after treatment.The result shows that the physical and mechanical properties of soil are improved obviously by using HDVM,and the experiment has got its anticipation.It is revealed that HDVM is appropriate for treating such a kind of soft soil along the coast. |
