摘要
不良冻土热融滑塌平面、剖面示意图,提取不良冻土热融滑塌特征,以此为基础,采用微分方程模拟热融滑塌温度场数值,以模拟结果为基础,结合热融滑塌实际情况,采用填埋碎石防治不良冻土热融滑塌,并制定相应的恢复对策,实现了不良冻土热融滑塌致生态破坏的防治及恢复。与现有的不良冻土热融滑塌致生态破坏的防治方法及恢复对策相比较,提出的不良冻土热融滑塌致生态破坏的防治方法及恢复对策,极大的提升了防治效果,充分说明提出的不良冻土热融滑塌致生态破坏的防治方法及恢复对策具有更好的性能。
This paper analyses the sketch maps of the plane and section of thermal thawing collapse of unfavorable frozen soil.Based on the characteristics of thermal thawing collapse of unfavorable frozen soil,this paper uses differential equation to simulate the numerical value of temperature field of thermal thawing collapse.Based on the simulation results,it combines with the actual situation of thermal thawing collapse,adopts landfill gravel to prevent thermal thawing collapse of unfavorable frozen soil,and formulates corresponding recovery countermeasures,so as to realize thermal thawing collapse of unfavorable frozen soil.The experimental results show that,compared with the existing methods of preventing and restoring the ecological damage caused by the thermal-thawing collapse of unfavorable frozen soil,the proposed methods of preventing and restoring the ecological damage caused by the thermal-thawing collapse of unfavorable frozen soil and the restoring countermeasures greatly improve the control effect,fully demonstrating that the proposed methods of preventing and restoring the ecological damage caused by the thermal-thawing collapse of unfavorable frozen soil have better performance.
