Abstract

Abstract:

A wind tunnel simulation test was carried out on two new type of magnesium cement material sand barriers to evaluate their windbreak and sand fixation benefits. The flow field structure， sediment transport and erosion of the honeycomb and square magnesium cement plate sand barrier were compared. The results show that：（1） Both the square and honeycomb magnesium cement board sand barriers form a deceleration zone. The honeycomb sand barrier has a smaller deceleration zone， and an accelerated jet is formed above the sand barrier. （2） The most obvious deceleration occurs in the first barrier， the wind speed reduction in the second barrier is weakened， and the wind speed reduction in the third barrier is enhanced. After the third barrier， the wind speed reduction continues to increase until a certain distance is reached. The wind speed reduction begins to weaken and tends to be stable as the distance increases. As the wind speed increases， the deceleration area of the sand barrier does not decrease significantly. （3） After the installation of magnesium cement board sand barrier， the reduction rate of total sand transport of honeycomb sand barrier is lower than that of square sand barrier. When the wind speed is not less than 12 m·s^-1， the distribution law of sand transport above the sand surface is summarized into two parts： when it is lower than the height of sand barrier， the distribution of sand transport follows the exponential decay function. When it is higher than the height of sand barrier， the distribution of sand transport follows Gaussian distribution. （4） The sand surface of honeycomb sand barrier is more stable than that of square sand barrier. Combined with field observation and material cost， honeycomb magnesium cement board sand barrier has a wide application prospect in the field of windbreak and sand fixation.
