摘要
饱和砂土地基液化对公路涵洞造成严重破坏。以土动力试验为基础,通过静、动力有限元分析,对公路路基—涵洞基础联合作用下地基土的抗液化能力变化状况进行分析,并根据研究结果给出考虑公路路基应力影响的地基液化情况。
Liquefaction of saturated sandy soil subgrade causes serious damage for highway culvert. On the base of soil dynamic experimentation, through static-dynamic finite element analyses, it presents the trans-formation of subgrade with soil anti-liquefaction ability under the united action of highway roadbed and culvert substructure. And the influential factors of the highway roadbed stress are analyzed.
