Monitoring Data Analysis of Piezometer in Xiao Langdi Sediment Tunnels
Whether the leakage taking place is an important basis for the safety evaluation of the hydraulic tunnels that the concrete liner was pre-stressed with tendons. Based on the long-term monitoring data of piezometers in Xiao Langdi pre-stressed sediment tunnels over operation period, the influence factors on the monitoring data of piezometer and the development of measured water pressure were analyzed. The results show that the variation of water level in the tunnel has no impact on the monitoring data of piezometers when the sediment tunnels were in service state; The variation of piezometers monitoring data closely related to the seasonal variation, it increased in rainy season and returned to normal in the dry season. The main reason resulting in the increase of water pressure measured by piezometer is the arising of external water level in rainy season. No leakage phenomenon was observed in Xiao Langdi sediment tunnels over operation period. Based on the monitoring results a conclusion can be made that the design requirements of anti-cracking and anti-leakage were satisfied in Xiao Langdi sediment tunnels.
