Study on lining structure technical condition assessment method for operational tunnel
Ying Guogang · Journal of Beijing Jiaotong University · 2013
Whether the operational tunnel lining structure technical condition is good or bad is directly related to the driving safety and pedestrian safety in the tunnel.Therefore,how to assess the operational tunnel lining structure technical condition reasonably is paid close attention by people.Considering the insufficiencies of existing tunnel lining technical condition assessment method in tunnel engineering circle,the conceptions of tunnel health degree and tunnel health degree function were put forward first.The tunnel was divided into several assessment units and then the inspection data were assigned to these assessment units.The one-to-one correspondence relationship between the inspection data and assessment results was established by tunnel health degree function.A segmented and quantified tunnel lining technical condition assessment method based on field inspection data was put forward at last.The efficiency of the assessment method had been verified based on engineering case.
