In this paper, the performance of rigid pavement of the tunnel is studied by couple analysis of multi-slab system with joint and the foundation.

本文通过对带接缝多板系统和地基的耦合分析来研究隧道刚性路面板的性能 ,研究中把地基假定为文克勒地基 ,路面板间的接缝假定为剪切弹簧单元 ,并用压缩矩阵简化法解算多板系统。

This paper aims at solving the problem of tracking beam and main beam pointing error in multi-planar antenna SOTM caused by different frequency between communication and tracking signal,the fundamental of tracking beam pointing error is analyzed,and a scheme based on phase-compensation technology applying.

文中针对多板天线"动中通"系统由于通信内容和信标信号间的频率差异造成的跟踪波束和通信波束指向偏差问题,分析了跟踪波束指向偏差产生的基本原理,提出了一种基于延时线加两级移相器相位补偿技术的误差修正方案,并通过理论推导和Matlab仿真,证实了方案的可行性和有效性。
