Two Important Problems on Defining Loads on and Dynamic Analysis to Shallow-Buried Structures
<正>The paper presents the investigation of(1) the effects of stress waves propagating in the structure roof material on the stresses over the roof span by FEM and the wave motion models,(2) the effects of rigid-body movement of buried structures on dynamic response of the structures by the lumped parameter model with three DOF.The results are(1) the effects of stress waves propagating in the structures,(2) Abrupt decrease of stress in FOAM HEST 1 is no result of tensile waves reflecting from the concrete-air interface at the bottom of roof,(3) the rigid-body settlement of the structure has a important effect pm the dynamic response of buried structures,In addition to these,discussion on results of FOAM HEST 1 in Ref.[1]and the method of predicting loads in buried structures in Ref.[2]will be found in the paper.
