摘要
目的探求倾斜超高层建筑传递高程精度的理论估算方法。方法采用数字水准仪和钢尺分段向竖直方向传递高程,直至顶层的变形监测点的高程精度估算分析。结果以数字水准仪精度和钢尺丈量的精度,结合国家的测量规范规定,估算分析得到楼层直至顶层的高程精度,且获得高精度。结论倾斜超高层建筑的传递高程,虽然难度大,传递高程困难,难以获得高精度的高程,但适当的施测方法经理论估算分析,可以测得高程的高精度。
Aim The object is to explore theoretic calculation method of carry-over accuracy about inclination of super high-rise.Methods Use elevator accuracy calculation to analyze the fact that digital level and steel tape carry over elevator subsection from vertical direction until the top level of deformation observation.Results The elevator accuracy from bottom floor to top floor was obtained by combining digital level accuracy as well as steel tape accuracy with our national specifications of survey to get high accuracy.Conclusion The conclusion is that although the difficulty of exploring carry-over elevator about inclination super high-rise building is big,carry-over elevation is difficult,and it is hard to get elevator of high accuracy,a proper occupied method can solve the problem and measure elevator of high accuracy by theoretic calculation analysis.
