黄茅根系抗拔承载力试验研究

为了探索黄茅草根系与土壤的接触特性,并分析其根系各因素对抗拔力的影响,文章通过对不同龄期的黄茅草进行抗拔力研究实验,发现草的根茎发达程度,即固土高度,固土土重,根系重量都很大程度上影响抗拔力,并总结出以上因素与抗拔力的数值模拟,发现随着根系的发展,其固土高度、固土土重、根系重量都增大,并均与抗拔力呈正比关系。

In order to explore the contact characteristics between the root system and the soil and analyze the influence of various factors of the root system on the pullout force,the experiment on the pullout resistance of the grass of different ages was carried out in this paper,and it was found that the rhizome of the grass was developed,that is,the height of soil fixation,the weight of soil consolidation soil and root system affect the pullout resistance to a great extent,and the numerical simulation of the above factors and pullout resistance is summarized.It is found that with the development of root system,the height of soil fixation,the weight of soil fixation soil and the weight of root system all increase,and all of them are related to the pullout resistance.
