APPLICATION OF GEOPHYSICAL METHODS IN SOLVING ENGINEERING AND ENVIRONMENTAL PROBLEMS Lawrence A. Anine, Department of Earth Science, Federal University of Petroleum Resources, Effurun. The use of geophysical methods in solving engineering and environmental problems has increased over the years in most developed countries like Japan. During the 60’s, when Japan was still in their developing era, geophysical methods were used in investigation of new construction such as tunnel, dams, buildings and so on. In the present era, geophysical methods are now used in investigating disaster prevention, maintenance of existing construction and soil and ground water pollutions. As a developing country and continent, various geophysical methods should be employed in solving various engineering and environmental problems because they play a vital role in solving such problems. This vital role played by geophysicists, especially in construction of new roads, railways and high-rise buildings will be reflected in the future because, for instance, during construction, huge amounts of concretes are been used and this requires huge amount of sands. So, if low quality sands are used, the performance or quality of the concretes will decelerate, and as such shortens its durable years. Such concretes can cause accident in the future due to its bad quality. Therefore, it is important to an engineer to investigate the health of these concretes (building materials) and this role becomes much more important in the future. Geophysical methods with non-destructive techniques will be employed in testing the construction. Geophysical investigation is employed not only during construction but also for maintenance of existing constructions. Most concretes construction will reach their durable years after about 15 to 20 years and these durable years needs to be extended in order to use them longer than before since the rate of new construction will reduce in the coming era of low rate of economical...
