本文通过室内无荷膨胀率试验,对宜昌市某一级公路改建工程项目路段的膨胀土进行了研究。重点分析了无荷膨胀率与时间、掺砂比例、初始干密度之间的关系,试验研究表明:无荷膨胀变形主要分为快速膨胀、减速膨胀和最终稳定3 个阶段;在初始干密度一定时,风化砂改性土的无荷膨胀率会随着掺砂比例的增大先迅速降低然后缓慢降低,风化砂改性土的无荷膨胀率对较大的掺砂量不敏感;在相同的掺砂比例下,风化砂改性土的无荷膨胀率随着初始干密度的增大会迅速增大,它们之间有很好的线性相关性,膨胀土在进行路基填筑时,控制初始干密度有助于减小其膨胀变形,保证路基填土的稳定性。

Time-varying formation tracking for uncertain second-order nonlinearmulti-agent systems
Mao-peng RAN, Li-hua XIE, Jun-cheng LI

Our study is concerned with the time-varying formation tracking problem for second-order multi-agent systems that are subject to unknown nonlinear dynamics and external disturbance, and the states of the followers form a predefined time-varying formation while tracking the state of the leader. The total uncertainty lumps the unknown nonlinear dynamics and the external disturbance, and is regarded as an extended state of the agent. To estimate the total uncertainty, we design an extended state observer (ESO). Then we propose a novel ESO based time-varying formation tracking protocol. It is proved that, under the proposed protocol, the ESO estimation error and the time-varying formation tracking error can be made arbitrarily small. An application to the target enclosing problem for multiple unmanned aerial vehicles (UAVs) verifies the effectiveness and superiority of the proposed approach.
