摘　　要：采用井筒内外井壁现场埋设传感器的方法,建立由计算机控制的自动监测系统,实测大屯矿区某混合井井壁施工过程及之后一段时间的受力和变形演变规律。对实测结果进行分析,研究内外井壁的综合变形规律,可以预测井壁的长期安全性,为井壁破裂的预防和治理提供科学决策的依据。For searching the stress and deformation law of blended shaft-lining during construction and initial operation, sensors were buried in interior and exterior wall of shaft-lining, and automated monitoring system was created. The stress and deformation law was obtained by analyzing the test results. With the law, we can forecast the long-term safety of shaft lining and provide scientific decision evidence for preventive and treating measures of broken wall.
