小浪底库区深层淤积泥沙干容重分析

摘要

The Xiaolangdi Reservoir deep sediment samples was achieved by low disturbance deep sampling equipment,early reservoir sedi-ment dry bulk,dry bulk density and extreme stable dry bulk density were calculated by the theoretical formula of dry bulk density based on spherical particles proposed by HAN Qiwei,compared with the measured data of field sampling and consolidation test data. The results show that the results of theoretical calculation and measured data and consolidation test data are in good agreement. It is suitable for analysis for dry bulk density of deep sediment in Xiaolangdi Reservoir.%利用低扰动深层取样设备获取小浪底水库的深层淤积泥沙样品，采用韩其为提出的基于球体颗粒的干容重理论公式，计算了小浪底库区淤积泥沙的初期干容重、稳定干容重和极限稳定干容重，并与现场取样的实测资料和固结试验资料进行了对比。结果表明：理论计算结果和小浪底实测资料、固结试验资料符合较好，适用于小浪底水库淤积泥沙的干容重分析。
