在对冻胀性上层中基础产生冻胀上拔机理分析基础上,突破传统基础防冻胀方法,提出了新型防冻胀技术。根据新型防冻胀技术要求,对所设计的可巧妙利用冻上层与环境具有的温度差作传热动力的传热元件进行了试验,试验表明,新型防冻胀技术可有效地阻断冻上层中未冻结水迁移的上升“通路”,极大地缓解冻上层的冻胀变形,从而保证基础的稳定性。
Based on the analysis of frost heaving uplift mechanism in the upper layer of frost-heavy nature, the traditional anti-frost heave method was broken and a new anti-frost heave technology was proposed. According to the new anti-frost heaving technology requirements, the designed heat transfer element that can use the temperature difference between the frozen upper layer and the environment as the heat transfer power is tested. The test shows that the new type of anti-frost heave technology can effectively block the frozen upper layer. The rising “path” of frozen water migration greatly alleviates the frost heave deformation of the frozen upper layer, thereby ensuring the stability of the foundation.
