ABSTRACT In formulas that use the probabilistic method to calculate the stability of the
CWR, the value of the cross-resistance of the track beds hasn’t fully taken into
account the influence of the type of the parameter combination of the track
bed, making the calculation results for a particular line undifferentiated. The
analogy of the trajectory of the lateral displacement of the trackless bed is
proposed. It is proposed that the lateral resistance of the track bed is also ambiguous
within the allowable lateral displacement limit, and equivalent randomization
is performed. Through the analysis of the characteristics of the
appearance parameters of the track bed, a calculation formula containing
multiple surface parameters for the lateral resistance of the track bed was established,
and the values of various factors were reasonably analyzed. The
purpose of this paper is to point out that in the stability evaluation formula,
the value of the lateral parameters of the ballast bed lacks the consideration of
the surface parameters. Based on the surface parameters, a model to evaluate
the lateral resistance of the track bed is proposed. It can be seen as a refinement
of the formula.
