Roadbed filling method and device based on permafrost field stability
The invention provides a roadbed filling method based on permafrost field stability, which comprises the following steps of: in a first construction stage, carrying out detecting to obtain a natural frozen soil upper limit position of foundation soil in a permafrost field, and filling a first layer of roadbed filler with a preset thickness; after standing for at least one freezing and thawing cycle, in a second construction stage, carrying out detecting to obtain an artificial frozen soil upper limit position of the foundation soil in the permafrost field; and if the upper limit position of the artificial frozen soil is higher than the upper limit position of the natural frozen soil, representing that the state of the permafrost field is stable, and carrying out next-layer roadbed filling construction. Filling construction of the next layer of roadbed is carried out under the condition that the stability of a permafrost field on the lower portion of the roadbed is guaranteed, and possible diseases caused when permafrost degenerates and the nearby hydrothermal environment changes are avoided; through multiple roadbed filling processes, the upper limit recovery of frozen soil after roadbed filling can be accelerated; the arrangement of corresponding frozen soil protection engineering measures can be reduced, the engineering amount is reduced, and the construction cost is saved.
本发明提供一种基于多年冻土场稳定的路基填筑方法，其包含：在第一施工阶段，探测得到多年冻土场中地基土的天然冻土上限位置，并填筑第一层预设厚度的路基填料；静置至少一次冻融循环后，在第二施工阶段，探测得到多年冻土场中地基土的人为冻土上限位置；若人为冻土上限位置高于天然冻土上限位置，则表征多年冻土场的状态稳定，进行下一层路基填筑施工。本发明的下一层路基填筑施工是在保证路基下部多年冻土场稳定的情况下进行的，避免了多年冻土退化，附近水热环境发生改变时，可能会引起的病害；本发明通过多次路基填筑过程，能够加速路基填筑后冻土上限的恢复；本发明可以减少相应冻土保护工程措施的设置，减少工程量，节约施工成本。
