呼伦贝尔市永冻土地区小桥涵基础研究

在准确掌握冻土区水文、地质、气象等资料的基础上,综合工程冻土学、陆地水文学、地下水动力学、热力学的基础理论进行温度场数值模拟,并通过典型性试验研究,总结出在季冻土地区进行公路桥涵建设的规律和方法,为在呼伦贝尔及类似冻土地区进行小桥涵施工提供指导,并进一步为在高寒地区公路、铁路桥涵基础、房屋建筑基础提供理论依据。

Research on the small bridge and culvert foundation in permafrost regions of Hulunbuir

On the basis of mastering the information of hydrology,geology,weather and so on accurately,simulating the temperature-field by integrating the basic theory of engineering cryopedology,land hydrology,groundwater dynamics and thermodynamics,and through the typicality experimental study,the rules and methods of the construction of the highway bridges and culverts in seasonal frozen earth regions are summarized,which can guide the construction of the small bridge and culvert in the frozen earth area such as Hulunbuir and provide theoretical basis to the construction of highway,railway,bridge and culvert foundation and building foundation.
