| 摘 要： | 试验研究表明,石灰改良下蜀黏土具有水稳性好、强度高、压缩性低的良好工程性质,可作为高速铁路路基填料,但其工程性质受多个因素的影响。结合室内试验,对石灰掺入量、压实系数、含水量、干湿循环、龄期等对石灰改良下蜀黏土作为填料的工程性质的影响进行了分析,给出石灰改良下蜀黏土用作高速铁路路基填料的合理建议。

| Abstract: | The experimental results indicate that soil "Xiashu clay" stabilized with lime has good engineering properties such as low water sensitivity,high strength,and low compressibility;therefore,the improved soil can be used as fill material in the construction of high-speed railroad embankment,but one has to take into consideration multiple factors when analyzing its engineering properties.Based on laboratory testing,factors influencing the engineering properties of improved soil as fill material are discussed.These factors include lime content in mixture,coefficient of compressibility,water content,wet-dry circulation,and aging time.Practical suggestions are proposed. |

| Keywords: | improved soil coefficient of compressibility water content engineering properties |
