Multilayered combination of protective structures is an importantmeans of effectively weakening the explosive shockwave. On this\nbasis, a ââ?¬Å?rigid-flexible-rigidââ?¬Â three-layer sealed structure was proposed in this paper and two models for the sealed structure were\ndesigned. Meanwhile, internal explosion tests of the two models were conducted. One model used foam concrete as the energy\nabsorbing material and the other used dense sand. The comparisons between the test results and the computed results obtained\nfrom the formulae were made, and the test results agreed well with the computed results. Test results showed that both models\nhad favorable energy-dissipating capacity, and the model that used foam concrete as the energy absorbing material had a superior\nenergy-dissipating capacity.
