Method for treating foundation in permafrost region
The invention relates to the technical field of frozen soil construction, and provides a permafrost region foundation treatment method. The permafrost region foundation treatment method comprises the following steps that in first preset time, pile hole drilling is conducted on a foundation; filling a filler with a preset temperature into the pile hole, and tamping the filler to form a pile body; and block stone foundation construction is conducted on the top of the pile body, and foundation sealing is completed within second preset time. The defects that in the prior art, as the ground temperature rises, if the protection principle is adopted for the high-temperature permafrost in the near-phase-change temperature state, the construction cost and the maintenance cost in the operation period can be greatly increased, and the effect is not ideal are overcome. According to the method, the maximum settling volume can be completed within a short time, the foundation treatment process is accelerated, the treatment effect is improved, and high practicability and economical efficiency are achieved.
本发明涉及冻土施工技术领域，提供一种多年冻土区地基处理方法。多年冻土区地基处理方法包括如下步骤：在第一预定时间内，在所述地基进行打桩孔；向所述桩孔内灌入具有预定温度的填充物，然后将所述填充物夯实进而构成桩体；在所述桩体的顶部进行块石地基施工，并且在第二预定时间内完成地基封层。本发明解决了现有技术中随着地温升高，处于近相变温度状态高温多年冻土若采用保护的原则会大大提高工程造价以及运营期养护成本，且效果并不理想的缺陷。本方法可在较短时间内完成最大沉降量，加速地基处理过程，提高了处理效果，具有较高的实用性和经济性。
