Permafrost roadbed pile foundation model test device
The invention discloses a permafrost roadbed pile foundation model test device, and relates to a permafrost model test device. The invention aims to solve the technical problem that the differential settlement of the permafrost pile foundation containing the ice layer under the action of uniformly distributed load is difficult to test through indoor tests at present. According to the device, through the hexagonal foundation model barrel and the uniformly-distributed loading sliding blocks, the effect that the pile unit bodies bear uniformly-distributed loads under the condition that the piles are distributed in a regular triangle in actual roadbed engineering can be simulated; the plurality of loading blocks are mutually independent to generate displacement, so that the differential settlement in the permafrost foundation can be intuitively reflected; the broken ice layer is additionally arranged on the basis of manually compacted frozen soil, and distribution of ice layers in the actual permafrost foundation can be reflected. According to the permafrost roadbed pile foundation model, the wet soil and the crushed pure ice chips are used for preparing the foundation soil, so that the ice content of the permafrost can be uniform, and the actual engineering condition can be well simulated through the permafrost roadbed pile foundation model.
一种多年冻土路基桩基础模型试验装置，涉及一种多年冻土的模型试验装置。本发明是要解决目前难以通过室内试验对含冰层多年冻土桩基础在均布荷载作用下产生的不均匀沉降进行测试的技术问题。本发明的装置通过六边形地基模型桶和均布加载滑块可以模拟实际路基工程中正三角形布桩情况下桩单元体在承受均布荷载的作用；多个加载块相互独立产生位移，可以直观的体现多年冻土地基中的不均匀沉降；本发明还在人工压实冻土的基础上增加了碎冰层，可以反应实际多年冻土地基中的冰层的分布；本发明使用湿润土与破碎的纯净冰屑配置地基土可保证冻土含冰量均匀，通过本发明的多年冻土路基桩基础模型可以很好的模拟实际工程情况。
