The demand for binocular tunnels is increasing recently because of construction conditions in the suburbs. The drifts advanced method is popular as a construction method of binocular tunnels. This tunneling method has some advantages of large bearings for bending moments and vertical loads. But this method includes some weak points of long period and complex works. This paper shows a design method of binocular tunnels without drifts conquering these weak points on the past experiences.
