地铁竖井联系测量三角形布设及解算取位的探讨
|
摘要
在城市地铁竖井平面联系测量中运用误差理论,联系三角形的最优形状进行了探讨。并指出在联系三角形解算时,使用函数型计算器计算时由于两钢丝绳之间的距离S1算的取位不足会导致正弦定理和余弦定理解算的β角存在较大差异。通过对工程实例进行研究,发现只有把两钢丝间距的计算结果保留到0.000 1 mm时,才能使正、余弦定理计算的β角相等,从而保证了井下起始边方位角的正确性和可靠性,避免因联系测量结果有误给工程带来不利影响。
In this paper,the optimal shape of the triangle in the plane contact measurement of urban subway was analyzed by using the error theory. Then the paper pointed out that when the contact triangle is solved,there are big differences between the sine theorem and the cosine theorem because of the location issues in the calculation of the length of the edge when using the function calculator.The author found that when the calculation result of the distance between the two wires is recent to 0.0001 mm,the angle of the cosine and the cosine theorem can be equal,which could ensure the accuracy of azimuth transmission and avoid the adverse influences that the measurement results lead to.
