通过多年冻土区桩基承载力现场试验,考虑房屋的正常使用和建筑采暖影响多年冻土融沉降,桩基础的承载力设计值应与地基土层的负摩阻力进行校正,试验结果对多年冻土地区建筑地基基础施工有一定的实用价值和意义,特别是对工程项目有很大的应用价值。 Through the field test of pile bearing capacity in permafrost region, considering the normal use of houses and the impact of building heating on the permafrost thawing and settlement, the design value of bearing capacity of pile foundation should be corrected with the negative skin friction of foundation soil. The test results for many years Construction of foundation soil in the permafrost area has certain practical value and significance, especially for the project has a great application value.
