# Distance to lateral edge of multi-layer backfill

Distance from cable to the side of the cable bedding layer.

All resistances $R_q$ are calculated once for the side with shorter distance to backfill boundary, and once for the other side.

 $\frac{W_{T}}{2} - \operatorname{abs}{\left(\frac{x_{b}}{1000} - \frac{x_{pos}}{1000} \right)}$ shorter distance to backfill boundary $\frac{W_{T}}{2} + \operatorname{abs}{\left(\frac{x_{b}}{1000} - \frac{x_{pos}}{1000} \right)}$ longer distance to backfill boundary
