| Abstract: |
| The stability of tunnel pit-wall in the depths underground is a complicated dynamic problem. To study the stability of tunnel pit-wall, many calculation methods of the tunnel pressure are put forward. Although there are many analysis methods in tunnel stability field, all sorts of exiting experiences and local measured work in construction spot are highly regarded during tunnel design and construction process. According as plentiful tunnel local measured data during construction, the dynamic stability analysis method of tunnel pit-wall in the depths underground based on gravitational field is put forward. Corresponding calculation formula and application examples are offered. |
