Zhang 1,2, a 1School of Civil Engineering and Architecture, Central South University, Changsha , China 2Hunan Urban Professional College, Changsha , China; azhangjiawen0622@163.com Keywords: bridge engineering; wind induced response; continuous rigid frame bridge; time domain analysis; spectral analysis; safety index Abstract: The fluctuating wind field is simulated for digital by using the AR method.
The fluctuating wind loads, which are related to the shape and height of the structure, are multiple-points random loads and one of the main dominating loads of the large structures in civil engineering.
Highly seismic resistant and torsional resistant capabilities make it appealing to the bridge engineers [2].

Laboratory Tests on the Improvement of Strength of Silt using Microbes Zhaoyang XU 1,2,Shaojin Wan 1 ,Yaoren Ma 2 (1.College of Civil Science and Engineer, Yangzhou University, Yangzhou 225009 P.R.China) (2.Department of Geotechnical Engineering, Tongji University,Shanghai 200092 P.R.China) Key words: Silt; Microbe; Tri-axial compression test; ESEM ; EDX ; Modification mechanism Abstract: Microbe technology is introduced for improving silt The metabolic outcomes and precipitation of microbes can glue the soil granule,plug mineral lattice crystal,simultaneously strengthen their shear resistance.Characteristics of silt before and after modification are compared by CU tri-axial compression test.
The latest research on microbiology claims that the life activities of microbes play a role in the modification of geotechnical engineering properties.
Since the beginning of 21st century, with the mutual penetration of microbiology, basic science and engineering science, people pay more attention to the use of biological technology in civil engineering.
Further studies are still necessary for the application of engineering practice.

Material science is an interdisciplinary field applying the properties of matter to various areas of science and engineering.
Introduction Mechanical engineering emerged as a field during the industrial revolution in Europe in the 18th century.
Mechanical engineering science emerged in the 19th century as a result of developments in the field of physics.
Mechanical engineering overlaps with aerospace engineering, metallurgical engineering, civil engineering, electrical engineering, petroleum engineering, manufacturing engineeering, chemical engineering, and other engineering disciplines to varying amounts.

However, the theory and technology related to this method haven’t ripened fully, so a further engineering practice is needed for verification.
