Rockmass structure is an inherent property of rock mass. The structural plane and rock block are the constituent elements of the rockmass structure which play an important role in the deformation of rockmass (Gu, 1979). The distinct effect of rock mass structure exists during the entire process of the long-runout rock landslide.It controls the deformation, failure mechanism and kinematics modes of the rock mass during the landsliding process. Although there are many theories, hypotheses and associated dynamics models for the long-runout landslide research, most of these models ignore the essential issue of the effect of rock mass structure. This paper systematically summarizes the features of different existing theories and dynamics models of long-runout landslide. It then focuses on the important issues of effect of rockmass structure on the key dynamics parameters, dynamics mechanism and dynamic process modeling of long-runout landslide, and puts forward potential research topics considering the effect of rock mass structure on dynamics of long-run out landslide.%岩体结构是岩体的固有属性.结构面和结构体是岩体结构的组成单元,当岩体发生形变时,这些单元会起到控制作用(谷德振,1979).长远程岩质滑坡中岩体结构单元往往伴随着整个滑坡运动的过程,这是由于岩体内在的结构控制着岩体变形、破坏的机制与运动方式.虽然目前存在多种关于长远程滑坡的理论假设和基于各种理论假设的实现模型,然而这些模型的大多忽略了岩体结构效应这一本质问题.本文在系统总结了目前已有长远程滑坡理论和模型的基础上,讨论了长远程岩质滑坡动力学关键参数,动力学机制和动力学过程模型中的关键岩体结构效应问题,提出了考虑岩体结构效应的滑坡动力学可能的研究方向.
