天然软土地基填筑路堤破坏模式分析及极限高度确定

Filling Embankment Failure Mode Analysis and Limit Height Determination on Natural Soft Soil Foundation

通过对中山市某公路软土路基试验段中的天然软土地基填筑试验,研究其填筑过程的破坏模式及破坏机理,分析路基填筑破坏与路基填筑高度关系,确定天然路基状态下的极限填筑高度,研究填筑速率控制标准,可用于指导工程设计和施工。

Combining with natural soft soil foundation filling test of one highway′s soft soil foundation test section in Zhongshan City,the paper conducts a research on failure mode and damage mechanism of filling process,analyzes the relationship between foundation filling failure and filling height.Meanwhile it determines the limit filling height under natural foundation state and studies on filling rate control criterion,which can be used to direct project design and construction.
