铁路隧道岩溶季节变动带整治技术研究

Study on remediation techniques of seasonal change zone for railway tunnel karst

以西成高铁小安隧道岩溶季节变动带整治工程为例,结合该隧道区岩溶发育的特点,对泄水洞新建排泄通道和还建利用原有岩溶通道的技术特点进行了研究,研究结果表明,两种技术措施能彻底消除铁路运营期间的安全隐患。

Taking seasonal change zone remediation engineering of Xiao’an tunnel karst on Xi’an-Chengdu high-speed railway as an example,integrating the karst development properties in the above-mentioned tunnel,the paper studies the technical features of the new spillway and original karst channel.The research results show that:both of the technical measures can completely eliminate the hidden dangers during the railway operation.
