| Abstract: | With the development of structure design method,applying the reliability theory into highway tunnel design is the developing trend today.The present development situation of reliability theory in highway tunnel was introduced.It is pointed out that there is few research on the statistical characterization about load of different spans and resistance factor of surrounding rock in research of highway tunnel reliability,which makes the probabilistic limit state design difficult in highway tunnel.In view of thi... |
