摘要
以某路基边坡为研究对象,通过在基岩与上部土体间以及抗滑桩与土体间设置分界面单元,真实地反映了工程的实际接触情况。在此基础上,详细分析了抗滑桩加固边坡桩土的作用机理。分析表明,第1排抗滑桩在坡体的稳定性加固中起着至关重要的作用,它对于阻止上部土体的位移和承担上部土体下滑力起着重要的作用。分析揭示了抗滑桩加固边坡土压力拱的形成机理与上部土压力的传递过程,指出了桩附近土体与桩间土体的位移和应力分布特征。
In this paper,taking a roadbed slope for an example, through setting interface elements between bedrock and the upper soil and between anti -slide piles and the soil surrounding them, the actual contact situation in engineering was reflected truly. Based on this, the interaction mechanism between anti - slide piles and soil was analyzed in detail. The results showed that the first row anti - slide piles play a crucial role for the stability of slope, and play an important role in preventing the displacement of the upper soil and bearing the sliding force. The mechanism of forming of soil arch and the propagation of upper earth pressure were analyzed and revealed. The distribution characteristics of displacement and stress of the soil in the neighbourhood of anti - slide piles and between anti - slide piles were presented.
