摘要
介绍了真空联合堆载预压法大致机理,并通过工程运用实例,对工程实际中的地表沉降,分层沉降,孔隙水压力,水平位移进行现场监测,实践表明:真空联合堆载预压法具有提高加荷速率、缩短工期、提高加固深度及减少工后沉降等优点.
The mechanism of vacuum & surcharge preloading method is introduced herein. Based on the actual application cases, the in-situ monitoring has been performed for the actual project on the surface settlement, settlement in layers, pore water pressure, lateral displacement, etc.of which the result demonstrate that the method mentioned herein has the following advantages: raising the rate of loading, shortening the construction period, deepening the consolidation depth and allevating the settlement after construction as well.
