摘要
研究目的:郑太高铁位于华北地区西部,穿越了晋中平原、太岳山区、长治盆地、晋城盆地和太行山区等多种地貌单元,有地形条件复杂、环境敏感区众多、不良地质集中等特点,而高速铁路技术标准高、工程安全要求严格,在进行复杂山区高铁选线时线路适应地形及绕避障碍的灵活性较差。该区域的其他铁路项目选线过程中也存在类似问题,尚未总结出一套行之有效的选线方法。随着该区域大原高铁、雄忻高铁、太绥高铁等高等级铁路项目陆续进入设计和建设阶段,亟需对郑太高铁复杂地质条件下山区综合选线技术进行研究总结,提出在该区域安全有效的选线理念。研究结论:(1)郑太高铁是该区域第一条穿越复杂地质条件的高速铁路,针对复杂地形和地质条件,尤其是煤矿采空区等不良地质特征,综合运用煤田古地理学、聚矿规律学、构造地质学、地层学、采矿学等多学科基础理论,结合线路综合选线技术,总结出该区域“经济选线定方向、地质选线找路径、环保选线提品质、工程选线控风险”的综合选线技术理念;(2)本研究成果可为复杂地质条件下山区综合选线提供技术支撑,为该区域内的线性工程规划和建设提供借鉴。
Research purposes:Zhengzhou-Taiyuan High-speed Railway is located at the western part of north China.It traverses various geomorphic units such as the Jinzhong Plain,Taiyue Mountain,Changzhi Basin,Jincheng Basin,and Taihang Mountain.It has characteristics such as complex terrain conditions,numerous environmentally sensitive areas,and concentration of adverse geological conditions.However,high-speed railway has high technical standards and strict engineering safety requirements.When selecting routes for complex mountainous areas,there is less flexibility in adapting the terrain and avoiding obstacles.Similar problems exist in the route selection process of other existing railway projects in the region,and an effective principal for route selection has not yet been summarized.With the high-level railway projects such as the Jining-Datong-Yuanping High-speed Railway,Xiongan-Xinzhou High-speed Railway,and Taiyuan-Suide High-speed Railway,which are gradually entering the design and construction stages in the region,there is an urgent need to study and summarize the comprehensive route selection techniques in mountainous areas under complex geological conditions for the high-speed railway.It is necessary to propose a safe and effective route selection concept.Research conclusions:(1)The Zhengzhou-Taiyuan High-speed Railway is the first high-speed railway that traverses complex geological conditions in this region.Considering complex terrain and geological conditions,especially adverse geological features such as coal-mine voids,this paper comprehensively apply multi-disciplinary basic theories such as coalfield paleogeography,ore accumulation law,structural geology,stratigraphy,and mining science.Combining comprehensive route selection techniques,a concept of"economic route selection for orientation,geological route selection for safe route,environmental route selection for quality improvement,and engineering route selection for risk control"is developed for the region.(2)This paper provides supports for comprehensive route selection under complex geological conditions in mountainous areas and offers significant references for linear project planning and construction research within north China.
