The invention discloses a soft foundation treatment method combining gas cavitation and charge neutralization, which comprises the following steps: digging a plurality of vertical shafts to the drainage depth at intervals in a preset place of a soft foundation, and digging sealing ditches at the peripheries of the areas where the vertical shafts are located; after the hole wall of the vertical shaft is stable, a pretreatment agent is put into the vertical shaft; sand cushion layers are laid in the areas where the sealing ditch and the vertical shaft are located; a water catchment channel of the earth surface is arranged above the sand cushion layer of the area where the vertical shaft is located; the sand cushion layer and the water catchment channel are covered with a sealing film, the sealing ditch is backfilled and compacted, and the sealing film forms a sealed space in the area where the vertical shaft is located; and a gas circulation system is installed, high-pressure dry air is filled into the sealing film to form flowing airflow, the dry air is gathered on the to-be-treated site, and the soft foundation is compacted while water in the soil is brought out. The pore water of the high-water-content soft soil foundation can be better drained, the purpose of drainage consolidation is achieved, the construction risk is small, and the cost is low.
本发明公开了一种结合气体空化和电荷中和的软基处理方法，在软基的预定地点间隔挖设多个竖井至排水深度，竖井所在区域的外围挖设密封沟；待竖井的孔壁稳定后，向竖井中投放预处理剂；在密封沟以及竖井所在区域铺设砂垫层；竖井所在区域的砂垫层上方布设地表的汇水通道；将密封膜罩于砂垫层和汇水通道之上，回填压实密封沟，密封膜在竖井所在区域形成密封空间；安装气体循环系统，在密封膜内充入高压干燥空气，形成流动气流，将干燥气体聚集于待处理场地之上，将土壤中水分带出的同时对软基进行压实。本发明更好排出高含水率软土地基孔隙水，达到排水固结的目的，施工风险小，成本低。
