摘    要:为控制软土地基公路拓宽工程中新旧路堤的差异沉降,提出一种新的软土地基处理方式,即综合应用刚性桩和竖向土工材料进行公路拓宽地基处理。为把握路堤荷载作用下综合应用刚性桩和竖向土工材料加固直接拼接方式的拓宽路堤工作性状,应用FLAC3D建立三维分析模型。通过数值模拟计算,从加固前后路堤的沉降、地基侧向位移和稳定性等方面进行了分析研究。计算结果表明:刚性桩和竖向土工材料的综合应用能够有效控制地基土体侧向位移,从而能够减小新老路基的总体沉降和路堤顶面的差异沉降,加固效果明显。

关 键 词:河北省  水资源  传统产业  转型升级

Abstract:For realistic problems of declining bearing capacity of water resources in Hebei Province, this paper builds a evaluation index system about the reasonable allocation of water resources and applies Intuitionistic Fuzzy Analytic Hierarchy Process (IFAHP) to empirical evaluate the index system in high water consumption traditional industries. Meanwhile, a two-dimensional traditional industry classification coordinates of "water resources allocation-traditional industrial economic benefits" is built, setting different traditional industries to different quadrant through the analysis of the utilization of water resources and economic growth of traditional industries in Hebei Province. And then put forward the path choice for the transformation and upgrading of traditional industries in Hebei province.
Keywords:Hebei province  water resources  traditional industry  transformation and upgrading
