山西黄土击实特性分析

Analysis on Compaction Characteristics of Loess in Shanxi Province

山西地处黄土高原地区,在水利工程、道路、城市基础设施的建设中,会大量采用黄土作为工程的填筑材料。由于黄土颗粒具有粉粒含量集中,结构疏松,质地均匀等特点,研究压实特性非常重要。对水利工程中收集的80组击实试验数据进行统计,分析了最大干密度与最优含水率、最大干密度与颗粒组成及级配的相互关系,分析结论可为进一步明确山西黄土击实特性提供参考。

Shanxi Province is located in the Loess Plateau region.In the construction of water conservancy projects,roads,and urban infrastructure,a large number of loess will be used as the filling material for projects.Due to the characteristics of loess particles such as concentrated silt content,loose structure,and uniform texture,it is very important to study the compaction characteristics.Based on the statistics of 80 sets of compaction test data collected in water conservancy projects,the interrelationships between maximum dry density and optimal water content,maximum dry density and particle composition and gradation were analyzed.The analysis conclusions can provide references for further clarifying the compaction characteristics of loess in Shanxi Province.
