渭河堤防填筑标准试验研究

Experiment on filling standard of embankment of Weihe River

依托渭河综合治理工程中堤防填筑标准试验,掌握了沿渭河流域几个地段土料的颗粒分布状况,分析了影响堤防填筑的主要因素。通过相对密度试验和击实试验得到渭河流域几个地段土料的填筑标准值,对试验标准值进行了统计分析。结果表明:粗粒土只有在较好的级配条件下、细粒土为最优含水率的情况下,土料才能达到较好的压实效果。最后得出几个地段的填筑标准控制范围值,此成果对渭河堤防填筑工程有一定的指导意义。

Relied on the test of embankment filling standard in comprehensive management project of Weihe River , the paper learned the distribution situation of soil material particle at several locations along the basin of Weihe river ,and analyzed the main factors affecting the dike embankment .Through compaction test and relative density test , it got the value of filling soil material standard along several lots of Weihe riv -er,and carried out statistical analysis for existing standards .The test got the result that only under better gradation of coarse -grained soil and fine -grained soil is case optimum water content , the soil material can achieve better compaction results .The value of control range of filling standard is gotten in several lots.The result has a certain guiding significance for the work of embankment filling of Weihe River .
