Abstract:
With exploitation, mining and artificialprecipitation, the consolidation settlement of the soil around the shaft lining creates a vertical additional force in the thick alluvium, which is the key reason for the rupture of the concrete shaft lining. Therefore, the determination of the additional force has important meaning to analyze and predict the stability state of the shaft lining. A new established method of vertical additional force was put forth by the inverse analysis of strain optimization based on monitored information in-situ, and the vertical additional force in a concrete shaft lining was determined, then the developed process of mechanical state from elastic to plastic in the concrete shaft lining and the change laws of stress and strain were gained, and a limit strain value was put forward for the purpose of monitoring an alarm in-situ.
Key words: thick alluvium; shaft lining; the additional force; inversion, forecast
