【摘要】：深部圍巖調(diào)熱圈參數(shù)(半徑和溫度)的確定是開展熱害防控技術(shù)研究的基礎(chǔ)。筆者提出了一種適用于現(xiàn)場實測的深孔固定埋設(shè)式測溫方法,給出了孔深預(yù)判公式,在調(diào)熱圈溫度與半徑一般數(shù)學(xué)模型基礎(chǔ)上推導(dǎo)了調(diào)熱圈半徑計算公式。根據(jù)孔深是否滿足測量要求,分別討論各情況下的調(diào)熱圈溫度參數(shù)處理計算公式,建議在孔深滿足測量要求時調(diào)熱圈溫度采用實測數(shù)據(jù)計算,在孔深不滿足測量要求時調(diào)熱圈溫度采用溫度與半徑一般數(shù)學(xué)模型計算。以廣西某深部巖體工程為背景,設(shè)計了埋深660m處CWSK1、CWSK2兩測孔參數(shù)。應(yīng)用深孔固定埋設(shè)式測溫方法,對測孔進行封孔作業(yè)與定期收集深孔溫度測量數(shù)據(jù)。通過對實測數(shù)據(jù)分析處理,確定出CWSK1測孔和CWSK2測孔的圍巖調(diào)熱圈參數(shù)分別為29.8 m、33.45℃與34.3 m、33.31℃。
[Abstract]:The determination of the parameters (radius and temperature) of the heat regulating circle in the deep surrounding rock is the basis of the research on the thermal hazard prevention and control technology. In this paper, a method of fixed embedded temperature measurement with deep hole is presented, and the formula of hole depth prediction is given. Based on the general mathematical model of the temperature and radius of heat regulating coil, the calculation formula of the radius of heat regulating coil is derived. According to whether the hole depth meets the requirement of measurement, this paper discusses the calculation formulas of the temperature parameters of the heat regulating coil in each case, and suggests that the temperature of the heat regulating coil should be calculated by the measured data when the hole depth meets the measurement requirement. When the hole depth does not meet the measurement requirements, the temperature of the heat regulating coil is calculated by the general mathematical model of temperature and radius. Based on a deep rock mass engineering in Guangxi, two pore parameters of CWSK1 and CWSK2 are designed at 660m buried depth. In this paper, the method of deep hole fixed embedding temperature measurement is used to seal the hole and collect the data of deep hole temperature measurement regularly. By analyzing and processing the measured data, the parameters of surrounding rock heat regulating circle of CWSK1 and CWSK2 are determined to be 29.8 m ~ (33.45 鈩，
