Research on the calculation of stochastic m-method of the anti-slide pile with the excavation of front soil

In this paper,the calculation process and the detailed calculation formulae of the normal m-method and the detailed reliability calculation m-method of anti-slide pile were firstly supplied when the soils in the front of pile needed to be excavated.Because the slide-body and steady-body often were gravel soil and soft rock which was weathered,it was appropriate to research and calculate the auto-correlation character with the "m" parameter of pressuremeter test.
