大型工程施工控制测量基础标石设计与实践

The design of the bench mark and practice for large-scale construction control survey

本文结合松原大桥工程施工控制基础标石建设实例,对大型工程施工控制基础标石的形状、结构、埋设深度进行设计,考虑当地的特点,设计的原则是标石不受冻融、振动、沉降对标体安全稳定性的影响;采用先进的方法进行现场埋设,标型新颖、风格别致。经建标两年后的观测检验符合设计要求,标体安全稳定,精度可靠。本文力求能给类似工程建设基础标石提供一些参考作用。

This paper taking the bench mark construction of Songyuan Bridge as an example, designed its shape, structure, and depth according to the local geology. The design principle is the bench mark can not be impacted by thawing and freezing, vibration, and settlement. The construction the advanced construction methods on--site buried is used; the bench mark has novel shape and unique style. The test of the bench mark built for two years accords with the design requirement and is stable safety, the precision reliable. It will provide the reference for a similar construction.
