岩体边坡水平位移影响因素的数据挖掘方法研究

影响高边坡岩体安全稳定性的因素较多。为了更好地研究影响边坡稳定因素的敏感性,从边坡安全监控分析的角度对岩体边坡外观测点水平位移,进行了影响因素聚类分析。应用Clementine软件对岩体边坡外观测点水平位移进行了影响因素关联挖掘。以开挖、降雨、时效和支护作为边坡岩体的荷载集,以边坡岩体外观测点水平位移作为响应集,得出对岩体水平位移影响程度大小排序依次为监测时间、坡表开挖强度、硐室开挖强度、降雨强度、锚杆支护强度和锚索支护强度的结论。根据分析结果可以在控制边坡岩体变形时抓住主要矛盾,为监测分析和工程决策提供依据。

Data mining method research of influence factors of slope rock mass horizontal displacement

Factors affecting the security and stability of high slope rock mass are more, in order to study the sensitivity of the factors influencing the slope stability better outside the rock mass slope,it"s analyzed the horizontal displacement by clustering analysis from the safety of the slope and applied the software Clementine by excavation, rainfall,aging and supporting as load set,the horizontal displacement as a response to observed the link factors .It"s concluded that the degree of impact on horizontal displacement of rock mass size sorting followed by monitoring the time table, slope excavation strength, the strength of cavern excavation, rainfall intensity, the intensity of bolting and anchor cable supporting strength.According to the analysis result,it can be seized the main contradiction in control of the slope rock mass deformation,and provided the basis for monitoring analysis and engineering decision.
