在施工中,利用数学知识,通过计算,同时运用电脑CAD制图配合全站仪,综合利用极坐标法、直角坐标法等放线方法,将圆弧线简化成折线,最终准确定位,会使圆弧放线变得很容易。刚果(布)外交部礼堂为圆形会议厅,其基础放线是一重点。本工程放线半径分别为16.5,19.5,22.5,25.5m以及主席台圆弧,柱网共有5条弧形轴线,其中4条弧形轴线圆心在建筑物内,另1条弧形轴线圆心在建筑物外。
In construction, the use of mathematical knowledge, through the calculation, at the same time using computer CAD mapping with Total Station, the comprehensive use of polar coordinates, Cartesian coordinates and other pay-off method, the arc will be simplified into broken lines, the final accurate positioning, will circle Arc line becomes very easy. The Congo (cloth) Foreign Affairs Department auditorium is a circular conference hall, and its basic payout is a key point. The radial radii of the project are 16.5, 19.5, 22.5 and 25.5 m respectively, and the arc of the podium is composed of 5 arc-shaped axes, of which 4 arc-shaped centers are within the building and the center of the other arc is between Outside the building.
