沿坪定化马断裂带发育数个大型或巨型滑坡。这些断裂带滑坡特点明显，成因类似，各滑坡一般发育多个次级滑坡体，滑坡岩土体由次生黄土、断裂带强风化带、断裂破碎带组成，具双层或三层结构。滑坡总体顺断裂走向下滑，历史上曾多次活动。近年来变形监测资料表明，断裂带滑坡目前处于匀速蠕变阶段，表现为蠕滑→拉裂（塑流拉裂）→次级滑坡体启动下滑的特征。它是在断裂活动、地震、降雨、人类工程活动等内外动力耦合作用下形成的，坪定化马断裂的长期活动为滑坡形成提供了前提条件，断裂带的岩土体性质是滑坡长期活动的物质基础，而降雨、地震、坡脚开挖等是滑坡体失稳下滑的主要诱发因素。因而，有必要进一步研究断裂带滑坡在内外动力耦合作用下的成灾机理，为滑坡灾害防治预警提供科学依据。

There are a series of landslides developing along Pingding Huama fault zone.The properties of these landslides are evident.The origin of these lanslides is similar.In fault zone landslide generally consists of one or more secondary landslides.The sliding mass has two layers or three layers, which are composed of deposited loess,strong weathering zone of fault and fault broken zone.The landslides slip along fault strike generally and re-slip time after time historically. According to deformation measurement data in recent years,the landslide is a stage of constant speed creeping deformation at present.The processing of their deformation presents to be creeping to tensile fracture (plastic flow tensile fracture)and then to junior landslide slipping.The landslide formation is in coupling of endogenic and exogenic geological processes that are fault action,earthquake,rainfall and human engineering activity.The long time activity of Pingding Huama fault provides precondition for these landslides formation.The rock-soil mass characteristics are material basis of landslides activity for ages,while rainfall,earthquake and slope toe excavation are mainly factors that trigger these landslides to lose their stability.Therefore,it is necessary to further study the mechanism of fault zone landslides in coupling of endogenic and exogenic geological processes so as to provide a scientific basis for the prevention and early warning of landslide disaster.
