加筋高填方路堤沉降与稳定性试验及数值模拟分析

The Experiment and Numerical Simulation Analysis of Reinforced High Fill Embankment Settlement and Stability

近年来,由于高速建设的快速发展,山区高速的建设也开始被人们重视。由于山区地形的复杂多变导致其道路的特殊性,所以对于其施工也提出了相对苛刻的要求,这就在技术方面对于其提出了很高的要求。以某一省属高速公路为背景,根据高填方路堤施工过程的工程技术特点,对于土工格栅在此类工程施工中的运用及其形变机理进行研究。在对现场实测数据进行分析后,借助于FLAC 3D有限差分软件,对比分析理论计算结果和实测成果,对理论模型的可行性进行了验证。

Taking a Provincial Highway as the background, according to the engineering technical characteristics of high fill embankment construction process, this paper studied the application and its deformation mechanism of geogrid in the construction of this kind of engineering. After analyzing the field measured data, by means of FLAC 3D finite difference software, it also compared and analyzed the theoretical calculation results and the measured results, which verified the feasibility of the theoretical model.
