高液限土在宁道高速公路中的应用

The Application of High Liquid Limit Soil to Ningdao Expressway

介绍高液限土的工程特性,利用试验数据分析施工区的高液限土特征。提出通过控制高液限土碾压时的含水率从而达到路基要求的压实度的工作思路,详细阐述在宁道高速公路利用高液限土充当路基填料所采取的技术措施。从填筑质量看,压实度全部达到设计要求,由此验证施工工艺是可行的。

The engineering characteristics of high liquid limit soil of construction area are analyzed, and the thought of meeting the need of degree of compaction by controlling the moisture content of high liquid limit soil is put forward and the construction technique of foundation of Ningdao expressway using high liquid limit soil as roadbed filling is expounded in detail. All the degrees of compaction are up to the designing goal. This verified the feasibility of the construction technique.
