| 摘要： | The damage of DOTD's inventory of 54-inch cylindrical piles in marine envionments has been catalogued. All the 54-inch pilings accessible via boat, with the exception of those on I-55 have been inspected on the surface. The cracking was not extensive and even the worst cracks were not in need of immediate remediation. The most extensive cracking was further investigated with help from a Federal Highway Administration demonstration boat. This boat was used to conduct underwater inspections on I-10 between Ramah and Whiskey Bay, on I-10 over the reserve relief canal, and on the Twin Spans between New Orleans and Slidell. In general, the damage uncovered during this investigation was found to be minor and only warrants monitoring. Therefore, in lieu of remediation guidelines, we have come up with revised inspection activities to be carried out during future underwater inspections. |
