Course description and aims

Rock grounds have larger strength and stiffness than the un-cemented soil ground. Furthermore rock is common geological formation at relatively deep depth. Therefore large scale structures, such as dams, bridge foundations, and deep underground structures, such as mountain tunnels and underground power station are constructed on or in rock ground. However, there are a wide varieties of the conditions of rock mass and properties of rock material. Evaluations of these conditions and properties, and proper design and construction based on the conditions and properties are critical for safe and secure construction and maintenance of the rock structure.
In this course the students will study about the mechanical properties of rock materials and rock mass, the application of various theory and analytical models used in rock engineering.

Student learning outcomes

The students will acquire the knowledge on the following subjects on rock as the foundation of various infrastructures, such as

1) Geological process of rock formation, 2)Mechanical properties of rock, rock and rock mass classifications、3) Site and lab investigation of rock, 4) Analytical model of rock mass, 5) Behaviour of rock mass, 6) Design and construction of structures in/on rock, 7) Case studies

Keywords

geological rock formation, rock and rock mass classification, strength and stiffness, fractures and discontinuity, rock slope, rock tunnel, large underground structures, dam

Competencies that will be developed

Intercultural skills Communication skills Specialist skills Critical thinking skills Practical and/or problem-solving skills
