摘要
对某摊铺路面基层公路沉降观测点临时加密,获得较多的沉降数据。以软土厚度和路堤高度为主要对象,考虑不同因素对软基沉降的影响。采用灰色关联分析,得出该工况下,软土厚度对沉降的影响大于路堤高度,并着重分析了软土厚度与沉降的关系,可为其它高速路段沉降预测提供参考。
By densely arranging settlement observation point in the paving pavement base of the highway temporarily,the study obtains more settlement data.Taking the thickness of the soft ground and the height of the subgrade as the main object,It takes into account the effect of different factors on soft foundation Settlement.The grey relational analysis in the conditions shows that the thickness of the soft ground influence on settlement is greater than the height of the subgrade.The paper mainly analyses the relations of the thickness of the soft ground and settlement,which provides valuable reference for settlement prediction of other high-speed sections.
