| 摘 要： | 通过对某高速公路挖方路基所在堆积体的工程地质特征调查、勘察以及变形监测，分析了不同区段变形差异及机制，总结出碎石型堆积体由于巨型块石埋于坡下部或者碎石含量及密实程度差异形成松动-压密区特征，最后提出堆载反压和抗滑支挡两种治理思路。

Deformation Analysis and Treatment Thoughts about Gravel Deposits along the Highway |
| |
| Abstract: | Through engineering geological investigation and deformation monitoring on the deposits in roadbed excavation along a highway, the deformation difference and mechanism between the sections were analyzed. Then it was generalized that the featured compaction-relaxation regions were developed in the gravel deposits as the result of huge stones buried at the bottom of the slope, or the differences between the gravel content and the densification degree. At last, surcharge reaction and anti-slide retaining were proposed as the treatment thoughts. |
