摘要: 为明确特长山岭铁路隧道单、双洞型式及其长度特征,对国内外310座特长山岭铁路隧道的实际工程案例进行统计分析,对比我国已建和在建特长山岭铁路隧道单、双洞的长度分布现状,并分析亚洲(除中国外)、欧洲国家特长山岭铁路隧道单、双洞的长度分布特征。研究表明: 1)国内长度10 km<l≤15 km的特长山岭铁路隧道中,已建单、双洞隧道数量比为181,在建隧道洞线型式基本选用单洞双线型式; 2)国内长度15 km<l≤20 km的特长山岭铁路隧道中,已建单、双洞隧道数量比约为11,在建单、双洞隧道数量比为201 3)国内长度>20 km的特长山岭铁路隧道中,已建隧道洞线型式基本选用双洞单线型式,在建单、双洞隧道数量比为52 4)截至2020年底,已建和在建特长山岭铁路隧道总数中,单洞隧道数量增长约30%,双洞隧道数量增长约1% 5)亚洲国家(除中国外)长度>20 km的特长山岭铁路隧道基本选用单洞双线型式,欧洲国家长度>20 km的特长山岭铁路隧道基本选用双洞单线型式。

Abstract: To clarify the characteristics of single and doubletube extralong mountain railway tunnels, a statistical analysis is conducted on 310 extralong mountain railway tunnels. The lengths of doubletube extralong mountain railway tunnels built and under construction in China and those in Asian and European countries are summarized. Statistical results show the following. (1) For the extralong mountain railway tunnels in China with a length of 10~15 km, the ratio of the single to doubletube tunnels built is 181, and the singletube mode is the most popular in the tunnels under construction. (2) For the extralong mountain railway tunnels in China with a length of 15~20 km, the ratio of the single to doubletube tunnels built is approximately 11 and that for the tunnels under construction is 201. (3) For the extralong mountain railway tunnels in China with lengths above 20 km, the doubletube singletrack is commonly used in tunnels built, and the ratio of the single to doubletube tunnels under construction is 52. (4) By the end of 2020, considering the total number of the extralong mountain railway tunnels built and under construction, singletube tunnels have increased by approximately 30%, whereas doubletube tunnels have increased by approximately 1%. (5) The mountain railway tunnels in Asian countries (except China) with lengths above 20 km are singletube doubletrack tunnels, whereas those in European countries are doubletube singletrack tunnels.

Key words: extralong railway tunnels, mountain tunnel, single tube, double tube, tunnel length, distribution characteristics
