Summary: | 碩士 === 國立臺灣科技大學 === 營建工程技術學系 === 81 === The strength characteristics of Taipei silty clay has been
tigated by many researchers using laboratory tests. The purpose
this study is to investigate the shear strength properties and
engineering properties of Taipei silty clay using in-situ
pressuremeter test. Besides, an automatic Ko-consolidation test
was established. The Ko test results are used to verify the
self-boring pressuremeter test. The results of pressuremeter
test indicate that the ratio of undrained shear strength to
effective tical stress for the normally consolidated Taipei
silty clay is 0.7. The normalized undrained shear strength from
laboratory test is about 0.35-0.40. The pressuremeter test
obviously obtain the higher undrained shear strength than the
laboratory test. The ef- fects fo testing disturbance and
partially drained may be the of error for the pressuremeter
test. These factors should be into account in the determination
of undrained shear strength. undrained deformation modulus is
also affected by the soil bance during test. The dusturbance
should be avoided as best as possible.
