秭归新滩链子崖危岩体,是长江上最危险的滑坡,是国家重点监测点。研究其数值仿真方法,具有重大的实践意义。本文利用AutoCAD中链子崖T0～T6缝区危岩体监测点位布置图和历年形变监测数据,来对链子崖危岩体进行二维、三维的数值仿真,并利用有限的监测点数据设计模型算法,结合Matlab强大的数字与图像处理能力来模拟使其可视化。通过对1996～2005年的数据进行分析处理,以图形的方式来显示其变形的特征及规律,对今后危岩体的破坏性和预测防护工作提供一定的依据。
Zigui Xin Tan Chain Cliff dangerous rock body, is the most dangerous landslide on the Yangtze River, is the national key monitoring point. Studying the numerical simulation method is of great practical significance. In this paper, two-dimensional and three-dimensional numerical simulation of the Zhiziya dangerous rock mass is carried out by using the monitoring points layout and the deformation monitoring data of the dangerous rock mass in the T0 ~ T6 seam area of the chain cliff in AutoCAD, and the finite monitoring point data is used to design the model Algorithm, combined with Matlab powerful digital and image processing capabilities to simulate its visualization. Through the analysis and processing of the data from 1996 to 2005, the characteristics and regularity of the deformation are displayed graphically, which will provide some evidences for the future destructiveness of dangerous rock mass and prediction and protection work.
