| 摘 要： | 临界填筑高度是高速公路工程中关注的一个问题，路堤填筑高度度小于临界填筑高度时，地基的变形和稳定均能得到控制。以往的研究认为一般高速公路临界高度为一个定值，而对其时间效应很少进行研究和应用。根据固结理论，研究了地基土强度在路堤荷载作用下的增长规律，并结合已有临界填筑高度的研究成果，分析了临界填筑高度度随时间的增长规律。在此基础上，对高速公路填筑工艺进行了探讨。

| Abstract: | Critical height is a key problem in expressway engineering. When embankment height is less than the critical height, settlement and stability of foundations can be controlled. The critical height is considered as a constant in the previous research, and its time effect is rarely investigated and applied. In the paper, the consolidation theory is used to analyze soil’s strength improvement under embankment load. Later, time effect of the critical height is studied based on its former results. At last, the construction skill of the highway is discussed on the aging effect results. |
