| 摘 要： | 为了研究青混凝土与柔性增强涂层材料两种防渗抗冻胀技术的有效性,采用有限元分析软件ADINA,对其进行温度场、变形场及应力场仿真分析,研究了衬砌板的冻胀变形及其法向冻胀力和切向冻胀力分布规律,并分析衬砌板的应力及破坏规律;通过与普通混凝土衬砌对比分析,指出采用沥青混凝土、柔性增强涂层材料等柔性防渗抗冻胀材料不仅能使衬砌板的冻胀量及冻胀力更加均匀,而且通过释放变形,可使其法向及切向冻胀力减小25%～46%,可有效控制衬砌渠道冻胀破坏. |

| Abstract: | The asphalt concrete and the flexible enhancement coating material combine both anti-seepage and anti-heave functions in solving channel leakage.This study uses finite element analysis software ADINA to model the temperature field,the distortion field and the stress field.The study investigates the liner plate's heave distortion,the normal frost heaving pressure,the tangential frost heaving pressure distribution,and also the liner plate's stress and destruction.Through a comparative study,the results show t... |
