为查明川藏铁路通麦至鲁朗段工程地质问题，合理选择线路走向，在分析遥感释译和区域地质资料的基础上，结合野外调查、物探、钻探、地应力测试和室内岩石试验，针对雅鲁藏布江缝合带具有的高地应力、高地温和水文地质问题3大特殊区域地质问题，开展通麦至鲁朗段隧道选线工程地质研究，提出该段工程地质选线原则。综合分析表明： 帕隆藏布北岸CK方案在区域稳定性、地应力和地温等多方面均优于两跨缝合带C1K方案。
To identify the engineering geological problems of the TongmaiLulang section of SichuanTibet railway, and reasonably choose the route, the engineering geological study is conducted on route selection of the TongmaiLulang section tunnel based on remote sensing interpretation and regional geological data, field investigation, geophysical exploration, drilling, insitu stress testing, and petrological experiments, and high crustal stress, high geothermal activities, and hydrogeological problems of the Yarlung Zangbo suture zone. Additionally, the principle of engineering geological route selection in this section is proposed. The comprehensive analysis shows that the CK scheme of Parlung Zangbo north bank is superior to the C1K scheme of twospan suture zone in terms of regional stability, insitu stress, and ground temperature.
