| Summary: | 碩士 === 國立中央大學 === 土木工程研究所 === 94 === Bimrock is a kind of rock which contains the composition of block and matrix, its mechanical properites can be influenced by heterogeneous and anisotropy. This research is in different proportion with cement and kaolin to make transversely isotropic specimen of bimrock, then evolute to probe on mechanical behavior.
The content of rock is an important parameter to estimate bimrock, this research use rotary scanner to pick specimen of bimrock and develope the image on the surface, use image process method to estimate the raito of specimen of bimrock.
The result shows that the increase of confining pressure cause he destructive force to raise,and heterogeneous strength to reduce. This research use Tien and Kuo(2001) failure criterion and FLAC program to analyze the strength、heterogeneous and failure mode.the result show that prediction and experimental data are fairly agreeable.
