| 摘 要： | 对真空-堆载联合预压法在电厂地基处理中实际应用的监测数据进行分析,得出了某些有益结论:真空-堆载联合预压能使地基产生较大的沉降速率而不至于失稳,同时产生向内的水平位移,从而使它比堆载预压具有更强的抗失稳能力。

| Abstract: | The paper analyzed the monitoring data of the actual application of vacuum-surcharge preloading in foundation treatment for electric power plant,so some useful conclusions are drawn: The vacuum-surcharge preloading can cause more settlement velocity without instability and more horizontal displacement into the foundation,Threrby the foundation improved by vacuum-surcharge preloading is stabler than that by the surcharge preloading. |

| Keywords: | vacuum-surcharge preloading surface settlement pore water pressure lateral dioplacement consoldation degree |
