通过埋设在桩端以下地基土中的孔隙水压力计实测出罐体施工前、充水、稳定及放水各个阶段桩端不同位置、不同深度处土体孔隙水压力，分析大型群桩基础地基的孔隙水压力分布及对压缩层的影响范围。提出了大型油罐地基桩基沉降计算深度与基础宽度的关系，对指导软土地区罐体群桩基础设计具有一定的借鉴作用。
通過埋設在樁耑以下地基土中的孔隙水壓力計實測齣罐體施工前、充水、穩定及放水各箇階段樁耑不同位置、不同深度處土體孔隙水壓力，分析大型群樁基礎地基的孔隙水壓力分佈及對壓縮層的影響範圍。提齣瞭大型油罐地基樁基沉降計算深度與基礎寬度的關繫，對指導軟土地區罐體群樁基礎設計具有一定的藉鑒作用。

The pore water pressure gauge was laying in the foundation soil under tip of pile to survey pore water pressure under different position and different depth at each stage before tank construction, full water, stabilization and flowing. We analyzed the distribution of pore water pressure and the influence range of compression layer for large scale pile group foundation. The relationship between large scale oil tank pile foundation settlement calculation depth and foundation breadth was presented, which was used for guiding the design of pile group foundation in the soft soil area.
