在设计钢油罐中,对地基的不均匀沉陷,要求是很严格的,石油化工部批准颁发的“金属油罐施工及验收技术规范”[炼化建401—74],第81条明确规定,基础不均匀下沉应不超过基础直径的1.5‰,最大不超过40毫米为合格,工业与民用建筑地基基础设计规范 TJ7—74,第39条规定允许不均匀沉陷为≤8‰,为了满足对不均匀沉陷的要求,在软弱地基上建造钢油罐一般常采用深基础或桩基础,在地基处理上要用很高的投资,而且施工工期要长,是很
In the design of steel tanks, the uneven subsidence of the ground, the requirements are very strict, approved by the Ministry of Petrochemical issued “metal tank construction and acceptance of technical specifications” [Refining and Chemical Construction 401-74], Article 81 clearly states , The basic uneven subsidence should not exceed 1.5 ‰ of the base diameter, the maximum not exceeding 40 mm is qualified, industrial and civil buildings foundation design specifications TJ7-74, Article 39 allows uneven subsidence is ≤ 8 ‰, in order to meet For uneven subsidence requirements, the construction of steel tanks on soft foundations usually uses deep foundations or pile foundations, which require a high investment in foundation treatment and require a long construction period
