隧道施工中进洞关系数据点建立的探讨

Study on Establishment the Data Points of Entry Relation in Tunnel Construction

进洞关系数据是隧道控制点与隧道施工控制点间的联系纽带,通过建立隧道进洞关系数据点,可以在隧道控制点与隧道施工控制点间实现中间过渡控制,它作为进洞方向控制点,直接影响到后续隧道施工质量和进度。本文详细地论述了隧道进洞关系数据建立的必要性和建立方法。在隧道施工过程中,根据现场的实际情况建立隧道的进洞关系数据点,将会给隧道施工带来便利条件。

Data points of entry relation are the vinculum between tunnel Control points and tunnel construction control points. The transfer control of tunnel Control points and tunnel construction control points can be realized by means of establishment of entry relation data points. As control point of entry direction, it has direct influence on the quality and progress of follow - up tunnel construction. The necessity and methods of establishing entry re- lation data points are elaborated in this paper. In the process of tunnel construction, it is important to establish the data points of entry relation according to the actual situation. It will bring the convenient conditions for tunnel construction.
