| 摘 要： | 研究目的:通过对拉日铁路地热隧道不同的地质、地热条件的分析,确定地热隧道线路方案的选线原则,并为地热隧道线路方案的选择和完善提供依据.研究结论:从选线来看,拉日铁路色麦至仁布段地热隧道具有典型的高原山区河谷地热铁路选线的特点.选线时,线路要尽量绕避雅江两岸的滑坡、错落、泥石流、岩堆、危岩落石、断层等不良地质现象,特别是要绕避地热发育地段;线路要尽量与地热分布带大角度相交,以最短距离通过.选出的线路应符合安全、可靠、合理、经济的的原则.

| Abstract: | Research purposes: Through the analysis of the geologic and geothermic conditions of the geothermic tunnel of Lhasa-Rikaze Railway,the principle of choosing the location of the geothermic tunnel of the Lhasa-Rikaze Railway is determined for providing the basis to determine the location of the geothermic tunnel. Research conclusions:From the railway alignment,the locations of the geothermic tunnels in the section between Semai-Renbu of the Lhasa-Rikaze Railway are in the plateau and mountain areas with valle... |
