| Based on the slope rock San Wan Road in Wanzhou District of Chongqing city as a typical analysis, on-the-spot investigation, numerical simulation analysis method, rigid body limit equilibrium method, the kinematics and other means, in-depth study of the problem of dangerous rock mass characteristics, the Chongqing area rock instability collapse instability mode, dangerous rock stability, rockfall motion path finally, dangerous rock body according to different situations, some treatment measures suggest that simple.1ã€Geological lithology in Chongqing area by soft and hard rock layers as the main feature, in the long-term weathering force and gravity, prone to differential weathering, produce crack deformation, formed. Failure analysis of this paper is mainly sand mudstone slope and stability.2ã€Through calculation and Simulation of rockfall path, can get the movement path, rockfall process maximum rockfall distance, kinetic energy of the collision, bounce height, however, reduced computation, simulation and calculation process of saving time and labor, to check and judge, time-consuming and laborious; in addition, path simulation can also be convenient to block set, are rockfall path simulation, can see the effect of prevention measures, and to provide basis for the prevention and treatment of dangerous rock.Rocfall software can be used to provide the basis for prevention and treatment of dangerous rock quickly, timely, can use the method of auxiliary checking, in order to improve the accuracy of.3ã€Anchorage, clear, comprehensive management support, seal rock cavity using methods such as rock measures, closed treatment on top of the fractured rock, and in the unloading zone beyond repair water drain construction, slope rockfall restraining net or retaining wall. Comparison of protective engineering scheme, feasibility of full of protective measures. |
