| 摘要： | Forensic engineering in case of cable bridges is the investigation of materials required for their, components made from them, structures or components that fail or do not operate or function as intended, causing personal injury or damage to the property or alternatively it means offering evaluation, reporting, and expert witness testimony considering prevailing or accidental Geotechnical and Environmental conditions. Causes of failure may be of deterioration of cables, anchorages, fluttering of deck slab due to high wind speed, heavy rains or poor workmanship, geological problems etc. These cable bridges must systematically be monitored with instrumentation (health monitoring) since the inception of these bridges (like in case of signature bridge in Delhi) and protected them from the risk of corrosion of cables, loosening of anchors and vibration etc. Efforts shall be made to have consequences of failure to be dealt critically besides retracing processes and procedures leading to accidents in operation of construction machinery before, during construction and after operation with a view to improve performance or life of a component, or to assist in determining the facts of failure and its solution. There are different types of suspension bridges (Punalur, Kerala, Laxman Jhula, Tehri Dam, Ramjhula etc) and cable bridges (Vidyasagar and Nivedita Setu WB, Bandra Worli Seal Link, Yamuna Bridge Allahabad, Akkar Bridge Sikkim, Signature bridge in Delhi, cable bridges in J&K and lndore etc) in India. The paper here describes problems experienced in India and abroad in such/similar bridges and their solution, in context of finding real causes of failure of cable bridges. |
