Bearing Capacity Basalt Rock Maharashtra

20.04.2021  Try taking lateral bearing capacity equal to 0.33 to 0.67vertical bearing capacity, with a further reduction near the surface where the rock isnt confined. 0.33 for when RQD is zero and 0.67 for when RQD is high. See links below for some options on near-surface reduction. This is of course a rough method meant for order-of-magnitude checking.
