摘要
论文以测量渤中25—1CEP组块底部尺寸为例，对大型组块的底部尺寸测量提出了一套全新的测量方法。在分析计算时，应首先建立单个立柱圆心坐标的数学模型，然后利用VB语言编写测量计算软件，再利用两点间距离公式计算各立柱之间距离。如此，可以利用切线平距法测量组块底部尺寸，这样不仅解决了实际组块建造空间视线障碍的问题，而且可以快速得出计算结果，大大提高了现场测量的效率。
A new method measuring bottom size of large module is introduced in this paper, which is applied to bottom dimension survey of the module in Bozhong 25-1CEP project. A model of center-line for each column is formulated. Based on the formula of distance between two points and by using specific VB programs designed for measurement and estimation, distances between those uprights are calculated respectively. The method of horizontal distance measurement is used to work out the size of tangent bottom of block. The method not only overcome the difficulty in vision, but also can produce fast results, which greatly enhances the efficiency of field measurement.
