Due to the threat of global warming and the accelerated melting of glaciers and permafrost, the stability of slopes in permafrost regions has received an increasing amount of attention from scholars. However, research on the stability of soil-rock road cutting slopes in high-latitude and low-altitude permafrost regions of the Greater Khingan Mountains in the Inner Mongolia Autonomous Region has not been reported. For this reason, a study of the stability of a slope with a high ice content in section K105 + 600 to K105 + 700 of National Highway 332 is conducted. The slope is 20 m high and the slope angle is 45°, and the risk of landslides on this slope under the action of freeze-thaw erosion is very high. Because of this, field in situ monitoring, indoor freeze-thaw tests, thermal parameter tests, and ABAQUS numerical simulation models are used to study the stability of the slope. After collecting the continuous temperature, moisture, settlement, and slope deformation data, it was found that the slope was undergoing dynamic changes. The creep of shallow slopes increased with the number of freeze-thaw cycles. After approximately 150 freeze-thaw cycles, the slope safety factor was less than 1, which means that the slope had reached the limit equilibrium state. Therefore, freeze-thaw erosion greatly reduced the stability of the slope. Hence, the stability of the slope must be protected during its entire life cycle. This study provides a reference for the design and construction of road cutting slopes in the high-latitude and low-altitude permafrost regions of the Greater Khingan Mountains.

呼伦贝尔多年冻土区土石方路Cutting边坡稳定性研究

由于全球变暖的威胁以及冰川和多年冻土的加速融化，多年冻土地区斜坡的稳定性受到了越来越多学者的关注。然而，关于内蒙古自治区大兴安岭高纬度和低纬多年冻土区土石方路cutting边坡稳定性的研究尚未见报道。因此，在332国道的K105 + 600至K105 + 700区域中，对含冰量高的边坡的稳定性进行了研究。斜坡高20 m，倾斜角为45°，在冻融侵蚀作用下该斜坡发生滑坡的风险非常高。因此，现场监测，室内冻融测试，热参数测试，并利用ABAQUS数值模拟模型研究了边坡的稳定性。在收集了连续的温度，湿度，沉降和边坡变形数据后，发现边坡正在发生动态变化。浅坡的蠕变随着冻融循环次数的增加而增加。经过大约150次冻融循环后，斜坡安全系数小于1，这意味着斜坡已达到极限平衡状态。因此，冻融侵蚀大大降低了边坡的稳定性。因此，必须在整个生命周期内保护斜坡的稳定性。该研究为大兴安岭高纬度和低纬多年冻土区的路cutting边坡的设计和施工提供了参考。在收集了连续的温度，湿度，沉降和边坡变形数据后，发现边坡正在发生动态变化。浅坡的蠕变随着冻融循环次数的增加而增加。经过大约150次冻融循环后，斜坡安全系数小于1，这意味着斜坡已达到极限平衡状态。因此，冻融侵蚀大大降低了边坡的稳定性。因此，必须在整个生命周期内保护斜坡的稳定性。这项研究为大兴安岭高纬度和低海拔多年冻土区的路cutting边坡的设计和施工提供了参考。在收集了连续的温度，湿度，沉降和边坡变形数据后，发现边坡正在发生动态变化。浅坡的蠕变随着冻融循环次数的增加而增加。经过大约150次冻融循环后，斜坡安全系数小于1，这意味着斜坡已达到极限平衡状态。因此，冻融侵蚀大大降低了边坡的稳定性。因此，必须在整个生命周期内保护斜坡的稳定性。该研究为大兴安岭高纬度和低纬多年冻土区的路cutting边坡的设计和施工提供了参考。浅坡的蠕变随着冻融循环次数的增加而增加。经过大约150次冻融循环后，斜坡安全系数小于1，这意味着斜坡已达到极限平衡状态。因此，冻融侵蚀大大降低了边坡的稳定性。因此，必须在整个生命周期内保护斜坡的稳定性。该研究为大兴安岭高纬度和低纬多年冻土区的路cutting边坡的设计和施工提供了参考。浅坡的蠕变随着冻融循环次数的增加而增加。经过大约150次冻融循环后，斜坡安全系数小于1，这意味着斜坡已达到极限平衡状态。因此，冻融侵蚀大大降低了边坡的稳定性。因此，必须在整个生命周期内保护斜坡的稳定性。该研究为大兴安岭高纬度和低纬多年冻土区的路cutting边坡的设计和施工提供了参考。冻融侵蚀大大降低了边坡的稳定性。因此，必须在整个生命周期内保护斜坡的稳定性。该研究为大兴安岭高纬度和低纬多年冻土区的路cutting边坡的设计和施工提供了参考。冻融侵蚀大大降低了边坡的稳定性。因此，必须在整个生命周期内保护斜坡的稳定性。该研究为大兴安岭高纬度和低纬多年冻土区的路cutting边坡的设计和施工提供了参考。
