土性和埋深对增阻推力的影响研究

Research on influence of soil property and burial depth on increased resistance thrust

针对土性和埋深对增阻推力的影响,采用模型试验方法进行了研究,利用正交试验法进行了模型试验,得到筒体在不同土体中由增阻力提供推力与所研究参数的关系,从而指导自行走掘进机的设计和施工。

Aiming at the influence of the soil property and the burial depth on the increased resistance thrust,the paper undertakes the research by adopting the model experimental method,applies the orthogonal test to have the model experiment,and concludes the relationship between the thrust by the increased resistance and the researched parameter of the shell in various soils,so as to direct the design and construction of the auto-walking roadheader.
