| description | The invention discloses a large-scale vibration liquefaction test design method which comprises the following steps: Stp1, a large-scale test pit is excavated, filled back with sandy soil and then saturated; Stp2, a water-resistant explosive and a pore water pressure sensor are arranged in the test pit; Stp3, a plurality of groups of single point explosion liquefaction tests are performed, and a single point explosion liquefaction prediction formula is established; Stp4, multi cartridge bag trial explosion tests are performed, and a multi cartridge bag explosion liquefaction prediction formula is established; Stp5, according to the prediction formulas, vibration liquefaction test system prediction parameters are obtained; and Stp6, multi-point explosion liquefaction verification tests are performed, and large-area vibration liquefaction test system design parameters are determined. Large-area vibration liquefaction test environment can be artificially simulated, and multiple purposes of accurately grasp of ac |
