特殊建筑物施工测量的质量控制

Quality Control on Construction Measurement of Special Building

我院教学楼结构较为特殊,平面、立面均为弧形;对平面弧线、立面弧线的测量控制,计算时用扇形及弦切扇为弓形,利用三角函数计算的结果指导测量,省略了大量的繁复计算,从而使施测简单,贯彻了宏观上的弧形局部上可作直线施测的道理。

The structure of the teaching building in CCIT is very special: viewed either from its plane or three-dimensional angle, it is arched. In order to control the measurement of plane and three-dimensional arc, it is necessary to make use of circular sector and circular segment when counting and guide the measurement with the result of trigonometric function counting. In this way, lots of complex calculation is omitted, the construction and measurement is simplified, which follows the principle that macroscopically arc can be constructed and measured linearly part by part.
