| Abstract: | A method is proposed, which uses single edge notch specimens of rectangular cross section to test the fracture toughness K_(IC) of cohesive soil. Through the tests of fracture toughness K_(IC) of cohesive soil performed in Xiaolangdi Hydraulic Engineering Project. The influence of dry unit weight and water content on the fracture toughness K_(IC) is also analysed. |
