摘要
季节性冻土在新疆分布广泛,冰冻期长达3-6个月之久。因此,抗冻设计是工程建设中必须重视的问题。其中冻土深度的合理确定是季节冻土区防冻设计的主要内容之一。本文通过调查研究和理论分析,对影响土壤冻结深度的气温、地下水位、土质和含水量等因素进行了分析探讨,提出了冻土深度合理的取值方法,为工程建设提供有益的参考。
Seasonally frozen ground are widely distributed in Xinjiang with froze-up lasting three to six months. So anti-freeze design must be paid high attention to in engineering constructions. Reson-ably determining freezing depth is one of the main design contents in seasonally frozen regions. Th-rough the investigation study and theoretical analysis, each impact of temperature, water table, soil and water content and other factors on freezing depth is discussed in this artitle. Reasonable deter-mination method of freezing depth is put forward, which may provide some beneficial reference for engineering construction.
