At present,the negative pressure source of the prefabricated vertical drains (PVD) in the soft soil foundation reinforced by vacuum precompression method is usually located at the top,due to the attenuation of the vacuum along the vertical direction,the effect of ordinary vacuum preloading on deep soil is relatively poor.Therefore,a drainage method combining the PVD and the reverse prefabricated vertical drains (RPVD) is proposed,the negative pressure source of the PVD is at the top of the drainage plate,and the negative pressure source of the RPVD is at the bottom of the drainage plate.The PVD and RPVD combined with vacuum precompression is applied to a foundation treatment project in Wenzhou,and the monitoring results of surface settlement,vacuum degree and pore water pressure show that the average consolidation degree reaches 93.1%.Under the same working conditions,the surface settlement value obtained by the PVD and RPVD combined with vacuum precompression numerical simulation is larger than the value of surface settlement obtained by PVD combined with vacuum precompression,and the growth rate reaches 12.9%.Under the same working conditions,the dissipation of pore water pressure in the range of 3-10 m obtained by the PVD and RPVD combined with vacuum precompression numerical simulation is significantly better than that of the PVD combined with vacuum precompression,and the foundation reinforcement effect is better.PVD and RPVD combined with vacuum precompression method is worthy of further popularization and application in engineering.
