| 摘 要： | 季节冻土区因基土冻融破坏而造成的渠道护坡工程的位移、破坏屡见不鲜，大型高地下水位渠道渠基土含水率高、冻胀性强、冰推力大，对护砌结构综合指标要求更高。室内模型试验与示范工程表明，格宾网垫护坡结构可有效地降低渠道边坡土体的冻前含水率，具有较强的基土冻胀、融沉适应性，而且又有较强的生态效果。将为进一步完善格宾结构的抗冻理论与工程实践提供参考。

| Abstract: | It is freguenthy seen that the freeze-thaw of the foundation could damage the revetment in seasonal frozen soilregions. In high ground water level condition, the compositive indexes of the large channel panels are higher because of the high moisture content, strong frost heave and powerful ice thrust in foundation soil. Based on the lab experiments and the demonstration projects, Gabion structures can not only reduce the moisture content before freezing effectively and improve the adaptability to the freeze-thaw of the foundation, but also restore the environment. The conclusions can beused as references for consummating the anti-frozen theories and practical experiences. |
