Abstract

The Gilbert Hill is situated west of the Andheri railway station on western railway line in Mumbai, India. The present hill is practically a vertical monolith that rises about 60 meters (200 ft) above the surrounding ground level. The hill displays beautiful vertical columnar jointing that extends from the top to the bottom. Because of its rare and almost unique occurrence the hill with columnar joints is important geologically and historically. Hence, this hill needs to be preserved. The jointing is very well exposed in the western, northern and eastern parts. In the southern part there is rolled down debris that covers the exposure of the columnar jointing. The paper deals with the effect of vibrations caused by the construction equipment on the jointed rock body, for which vibration studies have been carried out. The propagation of waves (vibrations) at various locations (points) in the area resulting from use of heavy construction equipment like vibratory roller, rock breaker, etc was studied. The induced Peak Particle Velocity (PPV) is then compared with the tolerable PPV specified in the available literature. Based on the results of vibration studies carried out measures to protect, preserve and conserve the Gilbert Hill are discussed.

Columnar Basalt – Vibration Study and Preservation Methods at Mumbai, India

Arlington, Virginia

The Gilbert Hill is situated west of the Andheri railway station on western railway line in Mumbai, India. The present hill is practically a vertical monolith that rises about 60 meters (200 ft) above the surrounding ground level. The hill displays beautiful vertical columnar jointing that extends from the top to the bottom. Because of its rare and almost unique occurrence the hill with columnar joints is important geologically and historically. Hence, this hill needs to be preserved. The jointing is very well exposed in the western, northern and eastern parts. In the southern part there is rolled down debris that covers the exposure of the columnar jointing. The paper deals with the effect of vibrations caused by the construction equipment on the jointed rock body, for which vibration studies have been carried out. The propagation of waves (vibrations) at various locations (points) in the area resulting from use of heavy construction equipment like vibratory roller, rock breaker, etc was studied. The induced Peak Particle Velocity (PPV) is then compared with the tolerable PPV specified in the available literature. Based on the results of vibration studies carried out measures to protect, preserve and conserve the Gilbert Hill are discussed.
