西伯利亚典型溢洪道冻融物理模拟与温度场分析
|
摘要
为了更加清晰的把握寒区溢洪道的稳定情况,由俄罗斯西伯利亚分院麦尔尼科夫冻土研究所的工程建设实验室、冰川中心工程实验室和中国科学院地质研究所联合开展研究,通过冻融物理模拟与建立温度模型的方法,指出土壤和防渗帷幕的斜面上存在压力;证实了溢洪道侧墙与土壤边界发生土壤剥落假设和冰层形成的假设;根据气候条件和地质条件,工程北部、工程主体、工程南部温度达到稳定状态的时间分别为8～14 a、15～21 a、21～43 a。
In order to grasp the stability of the spillway in the cold area more clearly, the engineering construction laboratory of the Melnikov Frozen Soil Research Institute of the Siberian Branch of Russia, the Glacier Center Engineering Laboratory and the Institute of Geology of the Chinese Academy of Sciences conducted joint research to build the temperature field analysis method through the freeze-thaw physical simulation. Three main conclusions were drawn from the analysis and simulation results. Firstly, pressure exists on the slope between the soil and the anti-seepage curtain. Secondly, the assumption of soil spalling and ice formation on the boundary between the side wall of the spillway and the soil. Lastly, according to climatic conditions and geological conditions, the northern part of the project, the main body of the project, and the southern part of the project reached a steady temperature need 8～14 years, 15～21 years, and 21～43 years, respectively..
