【摘要】：為對川藏交通廊道內(nèi)道路工程的選定線及安全建設(shè)和運營提供科學(xué)決策及防災(zāi)減災(zāi)依據(jù),在對擬建川藏鐵路和高速公路沿線滑坡崩塌災(zāi)害進行系統(tǒng)野外調(diào)查和遙感解譯的基礎(chǔ)上,查明了川藏交通廊道康定至林芝段滑坡崩塌的空間分布特征和潛在危害情況,結(jié)合已有川藏公路沿線崩滑災(zāi)害的危害特征和危害方式,對該段廊道內(nèi)滑坡崩塌災(zāi)害的可能危害方式進行了深入細(xì)致地歸納、分析和總結(jié)。研究結(jié)果表明:川藏交通廊道康定至林芝段共發(fā)育滑坡崩塌災(zāi)害488處,其中滑坡262處,崩塌(含溜砂坡)226處;對擬建道路工程存在潛在危害或影響的崩滑災(zāi)害共有148處,滑坡有89處,崩塌(含溜砂坡)59處。崩塌滑坡災(zāi)害對道路工程的危害方式主要有:(1)滑坡崩塌威脅隧道及其進出口安全;(2)滑坡崩塌推移、掩埋、損毀道路工程;(3)滑坡崩塌威脅站場、車站安全;(4)滑坡崩塌堵江斷道、淹沒道路工程;(5)滑坡崩塌轉(zhuǎn)化為泥石流、洪水等災(zāi)害鏈危害道路工程;(6)崩塌、溜砂坡沖擊、擾動、掩埋道路工程。
[Abstract]:It provides scientific decision making and disaster prevention and mitigation basis for the selection line, safety construction and operation of the road engineering in Sichuan-Tibet traffic corridor. On the basis of systematic field investigation and remote sensing interpretation of landslide collapse disaster along the proposed Sichuan-Tibet railway and expressway, the spatial distribution characteristics and potential hazards of landslide collapse in the section of Sichuan-Tibet traffic corridor from Kangding to Linzhi are found out. Combined with the hazard characteristics and hazard mode of landslide disaster along the existing Sichuan-Tibet highway, the possible hazard modes of landslide collapse disaster in this section of corridor are summarized deeply and meticulously. Analysis and summary. The results show that there are 488 landslides in the section of Sichuan-Tibet traffic corridor from Kangding to Linzhi, of which 262 are landslides and 226 are landslips. There are 148 landslides and 89 landslides that have potential hazards or impacts on the proposed road projects. Collapse (including 59 places of slide slope. The main hazard mode of landslide disaster to road engineering is: 1) landslide collapse threatens tunnel and its entrance and exit safety (2) landslide collapse goes on, buries, destroys road engineering and threatens the site of landslide collapse. The landslide collapses and blocks the river broken road, submerges the road engineering to transform the landslide collapse into the debris flow, the flood and so on disaster chain endangers the road engineering to collapse, the sand slope impact, the disturbance, buries the road project.
