Rock engineering is a complex field, which involves in-depth understanding and control of various characteristics of rocks, such as rock properties, rock structure, mechanical properties and stability. It is also a comprehensive discipline that combines engineering and rock mechanics, including theoretical analysis and application of rocks.
Rock mechanics are the science of studying the mechanical behavior of rocks and rock masses. The main contents of rock mechanics include the study of geological structure, geological process, geological environment and mechanical phenomenon, and the calculation and prediction of rock engineering parameters. Rock mechanics have close relationship with seismology, geotechnical engineering, geology, geochemistry, geophysical exploration, etc..
The calculation of rock engineering parameters such as rock strength and deformation is one of the research orientations of rock engineering mechanics. According to the characteristics of rocks, various parameters such as strength, deformation, physical properties, chemical properties and mechanical properties are measured and calculated, and then the rock engineering parameters are calculated. In order to improve the accuracy of rock mechanics parameters, scientists have developed a series of theoretical methods and mathematical models to calculate the rock engineering parameters and analyze the stability of engineering.
Rock mechanics laboratory and field testing is an important content of rock engineering. In order to accurately grasp the characteristics and parameters of rocks, it is necessary to conduct laboratory and field tests. The main methods of laboratory testing include uniaxial, triaxial, alternating axial and shear tests, etc., and the main methods of field exploration include shallow drilling, deep drilling, direct loading test, in situ measurements and tests, etc. The laboratory and field test indexes are also called rock engineering parameters.
Rock engineering mechanics technology not only provides a technical basis for the exploration and utilization of rocks, but also provides a reliable guarantee for the engineering construction of rock engineering. In practical engineering projects, the knowledge of rock mechanics and the process of rock mechanics testing are used to study the failure and stability of rocks in engineering, assess the stability of the engineering foundation, determine the safe mining range, evaluate its unstable factors and find effective countermeasures. It also provides scientific basis for the selection and application of rock reinforcement materials.
Rock reinforcement engineering is an important branch of rock engineering. It refers to the engineering activities which use reinforcing materials to make up or strengthen the rock surface and increase its stability. With the rapid development of underground engineering and the advancement of technology, the properties and types of reinforcing materials continue to increase, which are widely used in engineering support, slope protection, soil nailing, liquid injection and other applications, to ensure the safety of engineering and the long-term stability of underground environment.
In engineering practice, rock mechanics have wide application in the fields of environment, protection and development of resources, foundation treatment, mine engineering and rock engineering technology. For example, in environment engineering, the evaluation of rock engineering parameters is indispensable for the investigation of geological conditions, the determination of landslide risk and the excavation safety evaluation of geological environment. In resource protection and development, rock engineering parameters are used to quantify the resource properties and establish the safety evaluation system for large-scale underground works. In foundation treatment, rock engineering parameters are used for foundation treatments such as backfill, oil and gas drainage, grouting and strengthening; in mine engineering, rock engineering parameters are used to evaluate the stability of mine at various stages and to make decisions for mining operations; in rock engineering technology, rock engineering parameters are used to establish rock engineering related technology standards.
In addition, rock engineering is also widely used in civil engineering and engineering geology, such as plumbing features of slopes, tunnel foundations, seismic safety assessments, and assessment of landfill stability, to ensure the safety of civil engineering construction and engineering geology.
Rock engineering is a comprehensive subject, which integrates theories and practical applications, and is the basis of many other subjects. Rock engineering has broad prospects in the aspects of engineering exploration, environmental protection, resource development, foundation treatment and mine engineering, providing a technical basis for the safe and economic development of geotechnical engineering.
