| 摘 要： | Seismic rupture produced by active faulting causes ground surface fracturing and seriously damages buildings.However,the fracture traces are usually indistinct or non-visible because of complicated deformations in Quaternary unconsolidated materials,so their upper parts can hardly be discovered on exploratory trenches.The aim of this paper is to study the types of fault rupture and displacement in different loose deposit beds from a joint view of mega-,meso-,and microscopic scales,and to find the mark and method for timing the palaeoseismic rupture on exploratory trenches.
