Method for treating liquefied foundation through explosion and drainage
The invention discloses a method for treating a liquefied foundation through explosion and drainage. The method comprises the following steps: arranging a plurality of vertical drainage boards penetrating through a soil layer which is liable to be liquefied at intervals in a liquefied foundation region to be treated; burying explosives in the soil layer which is liable to be liquefied; igniting the explosives, and rearranging the soil structure in the liquefied foundation by utilizing the impact force generated by the explosives; squeezing water out, and discharging the water from the drainage boards. The method disclosed by the invention has the advantages that 1) the method provides vertical drainage channels, the instantaneous impact force generated by explosion can accelerate the dispersion of pore water pressure, so that the water in the foundation is discharged, and the purposes of realizing quick dense sedimentation and eliminating liquefaction are achieved; 2) the construction speed is greatly increased, and the construction period is shortened; compared with the method for treating the liquefied foundation through pile foundations, the method disclosed by the invention is low in cost, simple to operate, and good in liquefaction resisting effect; 3) the application range is extensive, and the method is applicable for general liquefied foundations.
