水闸基土冻胀破坏的主要形式为闸上、下游混凝土防护结构位移、鼓胀、裂缝、破碎等。经过对水闸基土冻害的观测研究，并采用塑料油膏处理裂缝，对基土充填灌浆堵漏防渗，用聚苯乙烯泡沫塑料板进行保温防冻的处理，取得最佳加固处理效果。本文通过基土冻胀破坏水闸的加固工程实践，提出加固工程技术要点及注意问题。
The main forms of flood damage of sluice foundation soil are the displacement of the upper and lower concrete protective structures, bulging, cracks and crushing. Through the observation and research on the freezing damage of the sluice foundation soil, the plastic ointment is used to treat the cracks, the filling and plugging seepage prevention of the base soil is carried out, the polystyrene foam board is used for heat preservation and antifreeze treatment, and the best reinforcing treatment effect is obtained. This article through the foundation soil frost heaving damage sluice consolidation engineering practice, puts forward the reinforcement engineering technical point and the attention question.
