Abstract
Crosshole seismic survey was conducted to decipher the nature of the exposed rock mass in Hussain Sagar Lake at Hyderabad to erect a monolithic Buddha statue weighing about 470 tonnes. The purspose of the survey was to determine the continuity of subsurface conditions between borehole locations. The technique consists of in situ measurements of travel time of the seismic waves generated by an impulse in one borehole, its reception in the other and computation of seismic velocity. Analysis of the velocity data provided necessary information regarding the soundness of the rock mass.
