| 摘 要： | 基于高速铁路对防止路基变形的严格要求，常常需要对用作路基填料的土质进行改良。文章通过对全风化花岗岩生石灰改良土的大量室内试验，研究了改良土在不同掺和比下液塑限的变化，在不同击实条件下最大干密度和最优含水率的确定及影响，以及无侧限抗压强度的影响因素，为花岗岩地段铁路客运专线路基的设计和施工提供参考。

| Abstract: | Because of the strict demand of the embankment soil for high-speed rail-way, improving roadbed filling has become a critical problem to be solved.Through indoor tests of the weathered granite which were improved with lime, we can observe the change of liquid-plastic limits in different proportions of lime, analyze the maximum dry density and optimum water content under different conditions of compaction and study the influencing factors of unconfined compression strength.The experiment could provide a reference to the design and construction of high-speed passenger special railway in weathered granite regions. |
