油田地基基础工程中易出现的问题是 :井点降水出水不畅 ,灰土挤密桩缩孔或塌孔 ,泥浆护壁成孔灌注桩钢筋笼偏位、变形、上浮 ,沉管灌注桩吊脚桩 ,挖方边坡塌方 ,混凝土基础干缩裂缝 ,砖基础防潮层失效 ,回填土沉陷 ,水池及油罐不均匀沉降。结合施工规范和工作实践 ,从气候条件、施工工艺等方面分析了其产生的原因 ,提出了相应的防治措施
The problems that are easy to appear in foundation of oilfield are as follows: poor water and water in well point precipitation, shrinkage or collapse holes in lime-soil compaction pile, deviation, deformation, , Slope collapse of excavation side, shrinkage cracking of concrete foundation, failure of brick foundation moisture barrier, backfill soil subsidence, uneven settlement of water tank and tank. Combined with the construction norms and work practices, the reasons for the occurrence are analyzed from the aspects of climatic conditions and construction techniques, and the corresponding prevention and control measures are put forward
