球罐支柱基础间的不均匀沉降差的测量及其控制是近年来提出的施工课题,对于大型球罐显得尤为重要,所谓球罐支柱基础不均匀沉降主要发生在水压试验时及投料运行中,因此,有效控制基础沉降差,对保证球罐的安全运行是很有益的。但是,至今国内现行的标准、规范制订得不够明确,使现场施工者在实施时不易执行。支柱基础间的沉降差的控制,主要包括如何测量及计算不均匀沉降差;对于已测定的不均匀沉降差如何判定及其处置对策,鉴于国内尚无详细标准可参考,笔者根据“日本高压气体保安协会”制定的《L.P.G 装置检查标准》secl,“贮槽及其附属件”K H K S The measurement and control of the uneven settlement difference between the spherical tank and the column foundation is a construction project proposed in recent years. It is particularly important for a large spherical tank. The uneven settlement of the so-called spherical tank and column foundation mainly occurs during the hydrostatic test and the feeding operation Therefore, it is very beneficial to ensure the safe operation of the spherical tank by effectively controlling the difference of foundation settlement. However, so far the current domestic standards and norms have not been formulated clearly enough, so that the construction workers in the field are not easy to implement in implementation. The control of settlement difference between pillars foundation mainly includes how to measure and calculate the uneven settlement difference. For the determination of uneven settlement difference and how to deal with it, in view of no reference to the detailed standard in our country, Security Association “developed” LPG device inspection standards “secl,” storage tank and its accessories "KHKS
