摘要： 结合西南地区某机场高填方试验段工程,以碳质页岩为主要填料,针对层铺厚度、压实遍数、冲击压路机的冲击势能以及行驶速度等参数,利用压实度、表面沉降和顶面强度为主要质量控制手段,进行填筑体冲击压实试验研究。冲击压实该种填料,在试验段施工中取得较好的压实效果。根据试验工程提出的冲压施工参数,可以指导该机场大范围施工。

Abstract: Based on the trial section of high embankment engineering of an airport in Southwest China,the impact compaction property of carbonaceous shale as a primary filling is studied.Aiming at different layer thickness,number of passes,dissimilarly impact energy and velocity,the degree of compaction,layer surface settlement and strength are used as quality control means.Parameters proposed according to the trial are proved to be satisfactory and is recommended to guide large scale construction of airport.

Key words: carbonaceous shale, filling, impact compaction
