| 摘 要： | 结合东营储油罐工程实例,在储罐加水试压期间,通过拓普康电子水准仪实测储罐环墙基础各点沉降,并按照国家规范计算复合地基最终沉降量,从平面倾斜和非平面倾斜两方面进行不均匀沉降控制分析.分析结果显示,采用CFG桩复合地基的储罐,竖向位移沉降量、平面倾斜、非平面倾斜、沉降速率各指标都满足规范要求.

| Abstract: | In the light of the oil tank construction in Dongying,the annular wall foundation deformation is measured by Topcon electronic during the time of water-filling preloading in this paper,and then the final settlement is calculated and the uneven settlement control is analysed from two respects——plane tilt and non-planar tilt.The results show that all the cumulative settlements of vertical displacement,plane tilt,non-planar tilt and settlement velocity can meet the requirements of related codes. |
