Study of Constitutive Model of the Schist under Natural and Saturated Condition

Abstract:

Taking the schist as investigative subject, which is the weak layer widely distributed in Yun Fu pyrite, Guangdong province, the deformation characteristics and strength properties of the schist rock mass are analyzed through laboratory uniaxial and triaxial compression tests. Based on the tests on natural and saturated schist, the elastic constitutive equations of the schist, considering the closing of micro cracks, are established; and the deformation characteristics and strength properties of water-weakening influence is analyzed. Through the tests, the deformation characteristics and strength properties of the schist are further understood, which can give some advices to the design of rock slope containing weak layers of the schist.
