摘要

40多年前，一个标准化的项目建造了一座相当独特的变形的五层三段砖住宅，该住宅由条形网格基础结合的驱动柱桩组成，目前正在调查中。介绍了该建筑技术状况的岩土监测结果。介绍了桩身实际长度的仪器控制分析和桩身完整性目视评价的方法和结果。确定了基础基底超变形的原因:桩端达不到设计点;桩基浸没在密砂中的破坏;初级热网破裂，导致桩侧面产生“负摩擦”效应等。

RESIDENTIAL BUILDING’S DEFORMATION ON PILE FOUNDATION

A considerably distinctive deformed five-storeyed three-section brick residential house erected over 40 years ago on drivenprismatic piles combined by a strip grid foundation by a standardized project is under investigation. The geotechnical monitoring results of the building's technical condition are presented. Methods and results of the instrumental control analysis ofthe piles' actual length and visual evaluation of their integrity are presented. The causes of the foundations base's excess deformation were determined: the inability of the piles' tips to reach the designed mark; the piles' destruction during their immersion in dense sands; rupture of the primary thermal network, which led to "negative friction" effect on the piles' lateralsurface, etc.
