| 摘 要： | 施工基准传递是超高层建筑施工中尤为关键的测量工作,垂直度监测是对施工基准传递精度的一个重要检核。目前常用的基准传递方法如激光准直内控法、全站仪观测外控法以及GPS测量外控法等,不同程度地存在着不足。文中结合某高层建筑施工,采用BDS/GPS组合定位测量外控法进行垂直度复测的实践,结果表明该方法可克服施工干扰严重的不利条件,有效传递施工基准,进行垂直度复测,相对于其他方法有明显优势。

| Abstract: | Construction datum transfer is a vital surveying task in the survey construction of high-rise buildings,and the perpendicularity monitoring is an important check on the accuracy of constructional survey datum transforming.Nowadays,the commonly used transfer methods,such as laser collimator internal control,total station internal control measurement and GNSS external control measurement method,have their drawbacks to varying degrees.Base on the verticality re-measurement practice of a high-rise building project in construction using BDS/GPS integrated positioning external control measurement method,this study indicates that this method can overcome the adverse conditions of severe construction interference and transmit the constructional survey datum effectively and precisely.The conducting of verticality re-measurement proves that the adopted method has obvious advantages compared with other methods. |
