三方交会法在高层建筑物倾斜测量中的应用

Application of Three Party Intersection Method in Declivity Survey of High-rise Buildings

针对前方交会法实施高层建筑物倾斜测量具体操作中的实际问题,提出了一种在三方交会情况下,通过增加多余观测,利用间接平差原理来确定点位的坐标平差值的方法。同时,根据三角形性质定理确定交会点位的最优值,评定其点位精度,其精度高于前方交会法,并与小角法倾斜测量结果进行了比较;通过实地测量成果验证了该方法的可靠性。

Because of the problems in implementation high-rise buildings declivity survey based on forward intersection method in the specific operation,this paper proposed a new method through the increase redundant observation method,the point to the square of the difference use the principle of paramezer adjustment. According to the nature of the triangle we determined the optimal value, and assessed its position precision, certified the position precision was higher than forward intersection. We compared the measurement method with small angle method. Through the measurement example results can verify the reliability of this method.
