摘要:
拟建的莫斯科至喀山高速铁路地处东欧平原，沿线地形平坦，地质构造运动轻微，工程地质条件简单。文章结合莫斯科至喀山高速铁路初步设计工作，利用沿线工程地质勘察成果数据，系统介绍了莫斯科至喀山高速铁路沿线工程地质条件，指出对铁路工程影响较大的主要工程地质问题是季节性冻土、软弱地基土、隐伏岩溶及地面塌陷三大问题，此外，沿线路堤合格填料相对贫乏，对高速铁路投资也存在一定影响。在工程设计中，针对岩溶及地面塌陷工程地质问题采取了绕避岩溶强烈发育及严重地面塌陷地段，多序次地表钻孔注浆加固浅表层岩溶塌陷地段、桥梁工程跨越岩溶发育及塌陷地段，清除换填、复合地基加固处理软弱地基土，采用换填、土体改良、保温及防排水等措施，减轻冻融对高铁工程危害。对于影响高铁投资的合格路堤填料，研究后采用远运合格填料措施。
Abstract:
The proposed Moscow-Kazan High-speed Railway is located in the Eastern European Plain where the topography is flat, the geotectonic movement is slight and the geological condition is simple. Based on the preliminary design for Moscow-Kazan High-speed Railway and engineering geological investigation achievement data along Moscow-Kazan High-speed Railway, this paper systematically introduces the engineering geological conditions along the line and points out that main engineering geological problems which have great influence on railway engineering are seasonal frozen soil, soft foundation soil and hidden karst and ground subsidence, in addition, the lacking qualified filler for embankment along the line also has a certain influence on the investment of high-speed railway. In engineering design, For karst and ground subsidence geology problems, in case of the strongly developed karst and heavy ground subsidence, avoidance measure is taken, in case of shallow-surface karst subsidence, the multi-sequence surface borehole grouting measure is used for reinforcement of the ground, the bridge is also built to cross the developed karst section and subsidence section; for soft ground soil, replacement after removal and composite foundation reinforcement measures are usually used; the soil replacement, soil improvement, heat preservation and water proof and drainage measures are taken to alleviate the hazards of freezing and thawing on high-speed railway. For lack of qualified embankment filling materials, it is decided to transport the qualified filling material from long-distance place.
