英文摘要：
The interaction between explosion waves in soil and underground structures is the theory basis of underground protective structures design. Based on the tests, the rational media dynamic con- stitutive relationships were introduced and the wave propagation problems were solved. The recent advancements of calculation models and analytical methods on the interaction between explosion waves in soil and underground structures were reviewed. They were categorized into three parts： the dynam ic constitutive models of soil, the explosion wave propagation in free field and the interaction between blast waves and underground structures such as box-framed structures, circular structures and horse- shoe structures. The conventional dynamic constitutive models of unsaturated soil and saturated soil were itemized in details. The integrated elastoplastic dynamic constitutive model for soil was intro- duced, which can reflect relaxation effects of soil. The research achievements for one-dimensional plane wave propagation in inhomogeneous or layered media and the explosion load for underground structures were emphatically described. The applicable range and main deficiencies of various calcula- tion models and analytical methods were analyzed.
