TUNNELS AND TERRAIN

LOS TUNELES Y EL TERRENO

The author recalls the necessity for preliminary geological investigations in all civil engineering projects. To supplement these investigations, it is recommended to use geophysical investigation techniques such as electrical and seismic methods. The problems of tunnel boring in different types of terrain are briefly reviewed, and several examples of tunnels in Spain are given: tunnels in granite, volcanic rock, metamorphic rock, slate, quartz, sand; pudding stone with a high content of siliceous materials, limestone and dolomite, limestone conglomerate and heterogeneous rock. /TRRL/
