The Influence of six kinds of combinations of different boundary conditions on the maintenance of homogeneity of atmospheric boundary layer in computational wind engineering was investigated.
Introduction Accurate simulation of the horizontally homogeneous atmospheric boundary layer (ABL) is important for evaluating the wind loads on structures, pollutants dispersion, the natural ventilation of buildings, the assessment of the pedestrian comfort and many other topics in computational wind engineering (CWE) which had significantly increased in last two decades.

Research on deformation forecasting of deep foundation pit supporting structure based on BP neural networks Yi Xue1, a, Lei Xub and Zhengzheng Cao c School of Mechanics and Civil Engineering, China University of Mining and Technology, Xuzhou, Jiangsu, 221116, China axueyi007@gmail.com, bpear.juice@163.com, ccaozhengzheng612@163.com Key words: BP neural network, deep excavation, deformation forecasting, supporting structure.
Excavation engineering is affected by many kinds of factors.
It is becoming the key and difficult point in geotechnical engineering.
Introduction In recent years, with the development of the construction, an increasing number of excavations engineering comes into use, and the difficulty of deep excavation engineering has been greatly improved.
In many engineering purposes accidents often occur in the construction phase.

This work is devoted to the development of a new type Rollover Protective Structure which absorbs the impact energy using shear energy absorber during a roll-over accident of engineering vehicles.
Introduction During a roll-over accident of engineering vehicles, the kinetic energy is absorbed mainly by the roll-over protective structure (ROPS).
The proposed method and structure provide a reference for application of shear energy absorber of the engineering vehicles.
