Abstract

Shree Mandir Parikrama Project (SMPP), Puri is an ambitious project of Govt of Orissa under its Augmentation of Basic Amenities and Development of Heritage and Architecture (ABADHA) Scheme for developing Puri as “World Class Heritage City”. The project is planned to provide essential amenities to the tourist, an opportunity to develop and give modern architectural design to the heritage structure and various Math around the temple and also protect the monument of vehicular pollution. A study to evaluate the critical impact of ground vibration induced by Heavy Earth Moving Machineries (HEMM) operational during various construction activities of SMPP Project was carried out as by CSIR-CIMFR Regional Research Centre Bilaspur. Comprehensive investigation has been carried out in different phases to analyze attenuation characteristics of ground vibration induced by HEMM and its associated cumulative impact on the various structures of Shree Jagannath Temple. Various combinations of HEMM such as Rock Breaker (120 Ton), Rock ripper, and high capacity Hydraulic Excavator etc. were made operational individually and collectively to measure the induced vibration and frequency using advanced seismograms. Vibration monitoring was also carried out at various critical structures of temple to assess likely damage due to amplification in the induced vibration under different permutation and combination of HEMMs operations. The attenuation characteristics of observed vibration data in different experimental conditions have been analyzed and compared with the widely-accepted vibration standards. The observed vibration data were analyzed and it was found that the vibration values induced by the construction equipment used in SMPP site, Puri were significantly less than the permissible safe limit of 2.0 mm/s. All the observed vibration values were lower than 1.0 mm/s barring few readings of cumulative operation observed at distance of approximately 3.0 m. Vibration reduces to less than 0.250 mm/s beyond a distance of 8.0 m. Faster decay of vibration may be attributed to the geological set-up of the site which is primarily sandy soil and gravel.
