江汉油田油建处于1991年在钟市集油田扩建过程中安装的4台5000m~3大型储罐,座落在水稻田,地基松软,当进行试水沉降时,发现基础不均匀下沉,严重的相临两点的高差达47mm,超过规范要求。采用降水法纠偏后,不均匀沉降明显好转,相临两点的最大高差降到21mm,达到规范要求。通过一段时间的使用,情况良好。
Jianghan Oilfield Oilfield built four 5000m ~ 3 large storage tanks installed in 1991 during expansion of Jimei Oil Field. Located at the paddy field, the foundation was soft and soft. When the test water settles, it is found that the foundation is unevenly subsided and seriously The difference between the two adjacent points up to 47mm, exceeding the standard requirements. After correction by precipitation method, the uneven settlement is obviously improved, and the maximum height difference between two adjacent points is reduced to 21mm, meeting the requirements of the code. After a period of use, the situation is good.
