Abstract
A method for foundation consolidation combining vacuum preloading and geomembrane bag assembly loading, which comprises: digging a slurry pit, filling mud into the slurry pit and conducting vacuum preloading pumpdrainage for multiple times, laying the geomembrane bag assemblies above the soft slurry seam processed through vacuum preloading pumpdrainage inside the slurry pit to form a plurality of loading layers, and laying the geomembrane bag assemblies by piling geomembrane bags. In view of the engineering complexity and uneven settlement resulting from conventional vacuum preloading using slag loading, geomembrane bag for loading to overcome the adverse effects of slag loading. In the present invention, the drainage system and the geomembrane bag assemblies are laid out to fully leverage their perspective properties, so as to improve the transmission of vacuity in the whole soil mass, speed up the drainage rate, and increase the degree of consolidation.
