| 摘 要： | 从砂土路基液化机理人手，结合黄河三角洲地区地基土工程地质特征，对该地区路基砂土液化做现场振动试验，找出影响砂土路基液化的影响因素，主要内因有土体的密实度、含水量和土体中是否存在软弱区；主要外因有荷载的大小、作用时间和荷载频率。并针对砂土液化的内外因，结合青银高速公路强夯处理案例展开分析，提出了处理方法。

| Abstract: | From the mechanism of liquefaction of sand subgrade,combining with the geo-engineering characteristics of sand subgrade in the Yellow River delta region,and carrying out roadbed vibration test of sand liquefaction in the region,elements which can effect liquefaction of sand subgrade are gained in this paper. It is identified that the internal factors are the density of soil,soil moisture content and the presence of weak areas in soil; the main external factors are the size of load,the role of time and loadi... |
