摘要
理论与实际相结合,通过崩塌落石对铁路工程及运营的影响分析,结合张集线工程实践,对崩塌落石形成原因、类型、运动形态等进行综合分析研究,利用运动学理论计算崩塌落石的运动轨迹和影响范围,揭示了崩塌落石的运动规律,据此为优化线路方案及工程设置提供依据,并以张集线线路方案优化为例予以说明。总结了玄武岩地区铁路选线及工程设置原则,为类似地区工程的设计和建设提供借鉴。
With analysis of the influence of rockfa11 on railway construction and operation and reference to engineering practices of Zhangjiakou- Ji＇ning railway, the formation of rockfali are comprehensively analyzed and studied covering the cause, type, shape and motion. The trajectory calculation and influence scope of rockfall kinematics theory reveal the law of motion of rockfall to provide the basis for optimization of the alignment and engineering settings, which are illustrated by the optimization of Zhangjiakou-Ji＇ning railway alignment. This paper summarizes the principles to guide route selection in basaltic areas and provides references for the design and construction of similar projects.
