... INTRODUCTION The stability of gravity dam has ever been calculated as a two dimensional problem by Using representative section to a direction of the stream. In case of an example shown in this report, there are several fractured zone Within the foundation rock at the site of a gravity dam...

... INTRODUCTION Recently in Japan, accompanying the development of such major traffic networks as super-express railways, express highways, and trans-strait bridges, many long span bridges have been constructed on weak foundation rock. It has thus become necessary to carry out surveys and tests...
