| Summary: | 碩士 === 國立高雄第一科技大學 === 營建工程所 === 94 === Taiwan is a small island but the mountain area is about 74 % and the population is
quite high. As the mountain area can afford a suitable recreational living environment
including good sight of view from the house and fresh air for the residents, the house
builder often would like to build houses in the area. However, as Taiwan is located in
the colliding area of Eurasian Plate and Philippine Sea Plate, the geological condition of
rocks in the mountain area is quite complicated and fractured as a result of the slope
failure often encountered. It is a valuable research subject for geotechnical engineers to
find the method for early evaluation of the slope stability to prevent the modification of
dangerous slopes in the planning stage.
The traditional analysis for the rock slope has limitation itself as the result of its
narrow applications in the subject. In 1985, Dr. Gen-hua Shi first proposed the Key
Block Theory by improving the traditional methods of Hemisphere Projection Method
and incorporating the Topology and Set theories. A series of computer programs were
also developed by Shi based upon the basic theory. The programs are quite user-friendly
and applicable for the systematic analysis for rock engineering.
This research introduces the basic Key Block Theory in the beginning. The
following work is to comment and verify the developed computer programs. The last
part is to apply the previous research results to the stability analysis of rock slopes in the
plane and wedge failure problems. The optimal attitude for the slope modification for a
slope is also included in the research. It can be highly expected to apply the developed
technique by using the computer programs to the reinforcement of unstable rock slopes
or the early evaluation of slope stability design in order to achieve the goals for safer
and more efficient slope constructions
