摘要:
西成客运专线路基占比较少，但由于山区高速铁路地形、地质情况复杂，路基设计具有一定的特殊性。本文分析了西成客运专线路基工程的主要特点，并提出了阿房宫车站垃圾坑、山区短路基、弱膨胀岩顺层高路堑边坡等设计重难点的处理方式。同时，也重新反思了隧道弃砟利用、风化岩的特性、防护栅栏设置等方面考虑不足的问题，可为同类项目提供借鉴。
Abstract:
Even the proportion of subgrade design in Xi’an to Chengdu high-speed railway is relatively small,but due to the complex terrain and geological conditions in the mountains, the design of subgrade is special. In this paper, the main characteristics of subgrade in Xi’an to Chengdu Passenger Dedicated Line are analyzed, and the key and difficult design points, like garbage pits of Epanggong station, short-length subgrades in the mountains,weak expansive bedding high-cut slope, are put forward. Meanwhile, some problems which are lack of consideration, like the utilization of the digging rocks of tunnel, features of weathered rocks, the setting of protective fence, are reflected, which could provide references for similar projects.
