碩士 === 國立臺灣海洋大學 === 河海工程學系 === 99 === Series of laboratory tests are performed to study the basic physical properties of laterite taleen from Taoyuan plateau. Unconfined compression permeability , and atterbeng tests are also performed for laterite with and(or) without additive of nano-clay, kaolinite and bentonite. Test results shows that (1) plasticity index (PI) of laterite increases gradually as content of nano-clay, kaolinite and bentonite increases;(2) unconfined strength decreases as PI increases, however, for laterite mixed with betonite more than 3%, unconfined strength increases as PI increases;(3) permeability is not related well with PI as shown in unconfined strength.
