| 摘 要： | 为了满足锚杆与围岩相互作用的红外辐射变化的处理要求,进行了实验红外热像数据的提取和锚杆作用区域的定量化分析。通过对受载锚固体的红外热像进行相减去噪和数据拟合,得到了锚杆与围岩相互作用的红外辐射等温线图,实现了锚杆横向作用范围的红外辐射温度场的提取,并将该方法应用于锚杆支护的巷道围岩变形及破坏过程的红外热像处理与分析研究,得到了巷道围岩变形过程中的多根锚杆共同的作用范围,为锚杆支护设计提供间距、排距的理论依据。

| Abstract: | For the demands of thermal infrared(TIR) radiation change regularity for TlR radiation detection experiments of interaction between bolt and rock,TIR image information extracting and quantitative analysis of bolts action zones were carried out.The IR isothermal fringes of the bolted books were obtained through thermal infrared image subtraction of bolted bocks and data fitting.The interaction ranges between bolts and rock were obtained and the bolted ranges of lateral directions were determined.The quantitative treatment methods were applied to analyze infrared images of bolted roadway also.The common acting zones of several bolts in the surrounding rocks are determined.The theoretical guides have been provided for the bolt supporting parameters design of spacing interval and array pitch. |
