Study on the technology of stabilization of sands using aeolian sand bag in the desert area

摘要

Based on "controlling sand to fix sand, managing sand with sand", aiming to the problems of sand hazard in the northwest desert area during the highway construction, the new technique of sand fixation is formed by bags of using widely distributed desert aeolian sand. The flow field characteristics of aeolian sand barrier with fins & nofins are analyzed by wind tunnel tests, the influence of sand barrier forms and specifications to wind speed reduction ratio and roughness are researched by field tests as well as sand fixation effect, the results can provide the guidance and application value to sand fixation engineer of the desert areas.
