geotechnical

Civil engineering construction in geotechnical engineering problems to promote the development of geotechnical engineering. For example in the civil engineering construction in the first encounter is soil stability problems. Soil mechanics theory the earliest contribution is the 1773 Kulun established Kulun law. The subsequent development of the Rankine ( 1857) theory and Fellenius ( 1926) circular sliding analysis theory. In order to analysis of soft clay foundation under the action of load settlement with time is a development process, Terzaghi ( 1925) development of one-dimensional consolidation theory.
Review our country nearly 50 years the development of geotechnical engineering, it is closely around the China Civil Engineering Construction in geotechnical engineering problem and development. Before reforming and opening, geotechnical engineering workers more attention in water conservancy, railways and mines in the engineering construction of geotechnical engineering problems, after the reform and opening up, with the development of the high-rise buildings,operable wall city underground space utilization and development of the expressway, rock and soil engineering researcher's attention more concentrated in the Construction Engineering, municipal engineering and traffic engineering construction geotechnical engineering problems in.
Civil engineering function, city, traffic speed, as well as the improvement of comprehensive home to environment becomes the modern civil engineering construction characteristics. Population growth accelerated development of the city, city changes process to promote big city in the number and size of the rapid development of. People will continue to expand the new living space, the development of underground space, to the ocean widened, building a bridge across the sea, submarine tunnel and the artificial island, reform desert, building highways and high-speed railways. Prospect of geotechnical engineering development, cannot leave modern to our country civil engineering construction and development trend analysis.
The development of a discipline is also affected by the level of science and technology and the related discipline development influence. After the two World War, especially in the nineteen sixties since, world science and technology develops very fast. Electronic technology and computer technology, computational analysis and testing capabilities, the geotechnical engineering computer analysis ability and the indoor testing technology has been improved and progress.
The progress of science and technology also prompted the geotechnical engineering in the new material and new technology to produce. As in recent years the rapid development of geosynthetic material called a revolution in geotechnical engineering. The modern scientific development is a characteristic of the discipline of mutual penetration,operable partition generate interdisciplinary and the continual emergence of new disciplines, this situation also affected the development of geotechnical engineering.
Geotechnical engineering is at the end of nineteen sixties to early 70's, the soil mechanics and foundation engineering, engineering geology, rock mass mechanics three gradually integrated and applied to engineering practice and the formation of a new discipline. Geotechnical engineering development will focus on the modern civil engineering construction in geotechnical engineering problem and will be incorporated in other disciplines .
New achievements. Geotechnical engineering involves the civil engineering construction of the rock and soil utilization, improvement or transformation, the basic question is to rock or soil stability, deformation and seepage problem. The author thinks that the following 12 aspects should be given attention in the study area, in twenty-first Century the development prospect of geotechnical engineering.
