摘要
结合工程实例，本文对大型煤气柜柜体变形观测方法进行了全面的论述，提出采用小角前方交会法精确测定立柱中心坐标，利用立柱中心坐标拟合柜体不同高度的几何中心坐标与半径值，据此分析柜体变形规律。这种变形观测为设计施工部门制定大修方案、改进柜体设计提供了可靠依据。
In this paper, taking a project as an example, the deformation observation method of large size waterless gasholder body is disscussed, in which the small angular forward intersection is proposed to determine the coordinate of pillar center, then the coordinate of that is used to fit the geometric center and radius of gasholder body at different height, based on those data, deformation law of waterless gasholder body is analyzed, that provides a reliable basis for working out the repairing scheme and improving the design of gasholder.
