摘要

拟建川藏铁路行走干印度板块与欧亚板块碰撞而隆升的川西及藏东南高原地带,沿线山高谷深,因其强烈的内、外动力作用及气候影响,段内沟谷边坡岩体卸荷作用强烈。本文在多次现场勘测的基础上,结合工程实例,对拟建川藏铁路沿线高陡边坡岩体卸荷带特征进行了分析,以期为川藏铁路科学选线提供依据。①拟建川藏铁路沟谷边坡岩体卸荷带因其大高差高势能的地貌、复杂活跃的地质构造、强烈的新构造运动、频繁强烈的地震及昼夜大温差的气候、强烈的水岩作用等工程地质条件而具有复杂性和多变性特征;②沟谷高陡边坡岩体卸荷带的形成和发展是内外动力耦合作用的结果;③沟谷高陡边坡岩体卸荷带发育的深度和广度及其稳定性是一个动态平衡过程;④沟谷边坡岩体卸荷分带的深度具有坡度和高程的差异性特征;⑤本文的研究结语对此段内公路、铁路等工程建设具有指导意义。
The proposed Sichuan-Tibet railway goes through high mountains and deep valleys located in the uplift western Sichuan and southeast Tibet plateau zones for the results of collision between India plate and Eurasian plate;with the characteristics of intensive unloading fracture zone of slope rock mass because of suffering strongly by the inter and external power action and bad climate condition in this area.Based on the site survey and engineering projects,analyzed the properties of unloading fracture zone of slope rock mass of the proposed Sichuan-Tibet railway,and provided a basis for the scientific alignment of the proposed Sichuan-Tibet railway.① The engineering geological conditions of unloading fracture zone of high steep slope of the proposed Sichuan-Tibet railway,that larger relative altitude and high potential energy landscape,complex and active geological formation,strong neotectonics,frequent and forceful earthquake and day and light larger difference in temperature climate,are complex and multivariate.② The formation and development of unloading fracture zone of high and steep rock slope in valley are the coupling result of internal and external power.③The development depth and scale of unloading fracture zone of high steep rock slope and its stability are the process of dynamic balance.④The depth of unloading fracture zone of high rock slope in varied slopes and altitude present different characteristics.⑤The research conclusions can be widely applied in expressway and railway engineering construction in this area.
