本文所讨论的圆形有压水工隧洞不衬砌计算,实质上就是半无限体中水平或者接近于水平的筒形圆管问题的求解。因此,它的计算方法不仅能用结构理论来计算岩石中应力是否超出岩石强度限制,而且也能用弹性理论和岩石力学研究成果来解决计算应力问题。 在所见到书籍中,专门讨论这些问题的理论几乎没有,但是技术上问题是很多的,作者在本文所研究的仅是静力计算问题。
The calculation of the circular pressured hydraulic tunnel that is not discussed in this paper is essentially a solution to the cylindrical tube problem that is horizontal or close to horizontal in a semi-infinite body. Therefore, its calculation method can not only use the structural theory to calculate whether the rock stress exceeds the rock strength limit, but also can use elastic theory and rock mechanics research results to solve the calculated stress problem. In the books I have seen, there are hardly any theories devoted to discussing these issues, but there are many technical issues. The authors have only studied static calculations in this paper.
