abstract = {<p style="text-align: justify;">A new simple mathematical method has been proposed to predict rock stress
around a noncircular tunnel and the method is calibrated and validated with a numerical
model. It can be found that the tunnel shapes and polar angles affect the applicable
zone of the theoretical model significantly and the applicable zone of a rectangular
tunnel was obtained using this method. The method can be used to predict the values
of the concentrated stress, and to analyze the change rate of rock stress and back to
calculate the mechanical boundary condition in the applicable zone. The results of the
stress change rate indicate that the horizontal stress is negatively related to the vertical
boundary load and positively related to the horizontal boundary load. The vertical
stress is negatively related to the horizontal boundary load and positively related to
the vertical boundary load. These findings can be used to explain the evolution of the
vertical increment in stress obtained with field-based borehole stress monitoring.</p>},
