摘要
地层沉陷导致位于该地区的隧道随之沉陷,直接影响到隧道的安全使用。隧道沉陷主要包括6种表现形式的移动与变形。本文研究了隧道沉陷的破坏特征,推导出隧道移动与变形的预报公式,讨论了隧道受到沉陷影响程度的预测与分析方法,初步提出了防治隧道沉陷的技术方案。最后,列举了一个隧道沉陷预报的实例。
A tunnel subsidence is caused by ground subsidence, and the security of the tunnel directly impaired. There are six models for tunnel subsidence.The characteristics of damaged tunnel with ground subsidence are studied in this paper. The predicting formulas of the tunnel movements and deformations are educed. The methods of analyzing destructive effects on the tunnel are researched. The measures of prevention and maintenance of the tunnel subsidence are discussed. Lastly, an actual example for predicting a tunnel subsidence is given.
