Vacuum combined surcharge preloading is a kind of drainage consolidation method, having many advantages, such as low reinforcement cost, short construction period and good reinforcement effect, and suitable used in foundation treatment in soft foundation. Based on vacuum combined surcharge preloading reinforcement project of one Sluice soft soil foundation in the east coast of Zhejiang Province, this paper introduced the in situ monitoring situation in the vacuum preloading process, mainly summarized the monitoring result of vacuum degree and surface subsidence, and found out the changes and connections of indicators in the preloading process. At the same time, the development process of vacuum combined with preloading and settlement is simulated by finite element method.
