对３５３平硐钢筋混凝土衬砌钢筋应力及拱圈温度缝开合度进行了计算分析，并建立了反映温度缝变化规律的数学模型。分析结果表明，３５３平硐工作性态正常。
The stress and the degree of opening of the arch of the 353-entry reinforced concrete lining are calculated and analyzed, and a mathematical model reflecting the variation of the temperature seam is established. Analysis results show that 353 adit work normal.
