连拱隧道的中隔墙受力分析

中隔墙是连拱隧道的中枢结构，也是重要的承载构件，其受力情况直接影响着隧道的稳定性和安全性。通过对中隔墙的断面形式及其受力情况进行分析，提出在连拱隧道中隔墙设计与施工过程中，应该全面考虑中隔墙的受力情况，采取科学的方法进行有效的改进，以保证隧道工程的经济性、实用性、安全性及稳定性。

Stress on Middle Wall of Arch Tunnel

The middle wall is the central part in the structure of arch tunnel and also an important bearing member, the forces on which directly impact on the stability and security of the tunnel. Based on the analysis of the form of cross-section and the situation of the stress, the paper puts forward the forces on the middle wall of arch tunnel should be fully considered in the process of the design and construction, to take a scientific approach to make some effective improvement to ensure the tunnel economy, practicality, safety and stability.
