The invention discloses a processing method for strengthening a vacuum preloading soft foundation by a direct-current electric field. A direct-current electric field operating well is arranged in a vacuum preloading soft foundation processing area, a direct-current power supply is installed, a positive-electrode discharge electrode or a negative-electrode discharge electrode is vertically arranged in the direct-current electric field operating well, the direct-current power supply is connected with the positive-electrode discharge electrode or the negative-electrode discharge electrode through a cable, the direct-current power supply is switched on in the vacuum preloading construction period, and therefore the direct-current power supply outputs direct currents which are transmitted to the positive-electrode discharge electrode through the cable, the positive-electrode discharge electrode discharges the direct currents to a soft soil layer in the soft foundation processing area, the direct-current electric field is formed in the soft soil layer between the positive-electrode discharge electrode and the negative-electrode discharge electrode, and direct-current electric field processing is performed on the soft soil layer of the vacuum preloading soft foundation processing area. According to the processing method for strengthening the vacuum preloading soft foundation by the direct-current electric field, the construction effect of processing the vacuum preloading soft foundation of mucky soil can be obviously enhanced, the purposes of reducing construction energy consumption and construction cost and shortening a construction period are achieved, and processing of the mucky soil soft foundation of a deep and thick layer can be effectively performed.
Description
technical field [0001] The invention relates to a soft ground treatment method, in particular to a direct current electric field enhanced vacuum preloading soft ground treatment method. Background technique [0002] Vacuum preloading method, as an important construction method for soft foundation treatment engineering, plays a very important role in coastal tidal flat development, land reclamation and other engineering projects. With the continuous development of the market and limited by the scarcity of sandy soil resources, the muddy soil formed by natural deposition or artificial dredging has increasingly become the construction object of vacuum preloading soft ground treatment projects. However, the existing vacuum preloading method has common difficulties in the soft foundation treatment of muddy soil, the main reasons are: [0003] 1) The silty soil has fine solid particles, high viscosity, and extremely low permeability, and the effect of vacuum transfer and drainage...
