Abstract

Abstract

The design and construction of twin tunnels are key questions in the study of shield tunnel.To obtain the influence of spaces on internal forces in lining,the model including layer,equivalent circle zone and lining was established.At first,the model was checked by calculating the field monitored data,and it was confirmed the one was relible and reasonable.Then the impact of space,covered depth and soil parameters on the soil stress and the internal forces in the lining were calculated.From the results of soil stress,it could be obtained that the unloading areas of tunnels come to overlap and the stress of the soil between the twin tunnels increased while the space decreased,then the internal forces was increased.From the result of the internal forces,the improving ratios of the maximal internal forces under various conditions were obtained.And the results showed that the impact of covered depth and the cohesion of soil on the improving ratio was little and the impact of the internal friction angle was notable.Then the improving ratio of design value of the maximal internal forces in the lining under various conditions was given.At last,with the comprehension of analysis results,some design and construction suggestions were given for the problems in shield twin tunnels.
