| 摘 要： | 堆载预压和真空联合堆载预压都是工程中处理软土地基的常用方法。通过舟山富通电缆项目地基处理工程项目中堆载预压和真空联合堆载预压施工的比较研究,得出真空联合堆载预压比堆载预压具有更高的施工成效效率,更好的沉降稳定性和沉降性,以及水平位移量更小,使周围软弱边界的变形处于较为稳定的状态。

| Abstract: | Surcharge preloading and vacuum surcharge preloading are common methods to deal with soft soil foundation in engineering. Through the comparative study of surcharge preloading and vacuum surcharge preloading(the foundation treatment project of Zhoushan Futong cable), it can be seen that the efficiency of vacuum surcharge preloading has higher stability and better settlement, horizontal displacement and smaller deformation of the surrounding.It can make weak boundary has a stable state. |

| Keywords: | surcharge preloading vacuum surcharge preloading layer settling surface subsidence horizontal displacement of deep soil |
