一、工程概况本工程为4×2万 m~3油罐群,罐体直径40.5m,座落在胜利油田孤岛首站西北。场区地质为第四纪黄河冲淤积新近粘性土,地质勘探资料表明,从地面以下8m～16.5m 之间是淤泥质粘土层。设计采用梅花形砂袋井堆载预压法处理地基,桩长18.5m,桩径10cm,桩中距1.5m,加固范围φ45.1m。
I. Project Overview This project is a 4×20,000 m 3 tank group with a tank diameter of 40.5m and is located in the northwest of the first station of Gudao Island in Shengli Oilfield. The geology of the site is the newly-occurring cohesive soil of the Quaternary Yellow River. The geological exploration data indicate that there is a muddy clay layer between 8m and 16.5m below the ground. The design adopts the pre-compression method of pile-shaped preloading with plum-shaped sandbags. The length of the pile is 18.5m, the diameter of the pile is 10cm, the distance between piles is 1.5m, and the reinforcement range is φ45.1m.
