← HistoryWhich outcome arises when subsurface drainage of the Taj Mahal's raised platform weakens its support, especially near pietra dura inlay?
A)Differential settling increases stresses✓
B)Uniform subsidence avoids cracking
C)Inlay patterns become misaligned vertically
D)Lime mortar becomes more cohesive
💡 Explanation
Elevated moisture undermines specific support areas because differential settling introduces stress concentrations via uneven load transfer—a kind of Consolidation settlement. Therefore, structural integrity declines with intensified, not uniform, settling, because inlay misalignment occurs at later stages, rather than earlier increased stresses.
