汾河太原城区治理南延伸段渗流特性试验研究

Experiments of Infiltration Characteristics of the Southern Extension of Fenhe in Taiyuan

汾河太原城区段治理美化二期南延伸段,由南内环桥向南延伸3.7 km。试验时为原始河道,土质为细沙土,部分为回填土。试验应用双套环法测试土层的饱和导水率,确定土层的入渗特性。并建立入渗特性与颗粒级配之间的对应关系,为工程设计提供可靠的试验数据,同时对工程的施工与管理运行具有重要的指导意义。

The second phase of beautification of the section of Fenhe in Taiyuan extends from Nanneihuan Bridge for 3.7 kilometers.In the experimental part,the river is original,with fine sands and some backfills.Double-ring testing is used to test the saturated hydraulic conductivity of the soil,determine the infiltration characteristics and construct a relation between infiltration and grading particles,which may provide reliable experimental data for construction design and may be of guiding importance for the construction and management.
