... rock, a strongly foliated and fractured zone, a cataclastic zone and a central zone of cohesionless material. Within this sequence the intensity of fragmentation of the rock mass increases towards the central zone. Surface and underground observations are confirmed through detailed study of borehole...

.... The parameters cf operation and state of rock stress assumed for other cases of computor modelling are summarized in Table 2. (1) Extension of fractured zone Calculated results for progressive exten- sion of fractured zone are illustrated in Fig.5. Read E.If.n,L. m ~ Define To for each element I, Calculate CT...

... stability on civil engineering. On the other hand, it is a common knowledge that the rock masses have bedding, Schistosity, joint and crack by weathering, or fractured zone and fault within slope. These become to form a discontinuous plane or a weak layer mechanically. For that reason, it is well known...

... 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...

... and a volume of 7.4 million m3. Construction was completed in 1976 and by 1979 reservoir had filled.(Figure 1.) The bedrock of the dam site is composed mostly of granite and in the vicinity of the right-bank of the dam crest and in the directly contact zone of the core at Streambed exist fractured zones...

... INTRODUCTION In public works it is very important for design and execution of work that location, width, dip, nature, degree of fracture, strength, and water content of fractured zone are clarified beforehand, and so investigationedand tests are done. The seismic refraction method...

In spite of many studies on the rela- tion between the theoretical groundwater flow and the geologic factor in the bed- rock, the actual behavior of groundwater flow is very complex and there have been few studies especially on the actual ground- water flow in the bedrock...
