摘要	In order to acquire the failure mechanism and anti-collapse measures of masonry structures under debris flow, this paper established a three-dimension fluid-solid coupling finite element analysis model by means of the finite element software LS-DYNA. The failure mechanism of masonry structures under debris flow were investigated by observing the deformation of structure, the energy of system and the displacement and velocity of key points. According to the failure mechanism of masonry structure and referring to the current codes and engineering practice, three anti-collapse measures were proposed, including increasing constructional column section size, reducing housing width size and lowering the structure height. The numerical results show that the plastic deformation of constructional columns can be reduced insignificantly by reducing housing width size and/or lowering the structure height; the impact resistance of masonry structure can be effectively increased by increasing the section size of constructional columns. ©, 2015, Tsinghua University.
