基于高填路基的力学特性进行数值分析,通过加载和加筋与否以及不同加筋部位条件下的应力与位移分布特性分析,阐述了高填路基施工过程中加载、填筑施工工艺等方面的质量控制以及填筑体稳定性安全施工控制与对策.分析指出,分层辗压、堆载以及工程荷载是高质量高填路基与安全施工控制的必要条件,且分层辗压工艺应注意不同部位位移不同特性;推荐采用中部加筋来改善填筑体应力状态以加强高填路基的稳定性,并应在路基下部与中部铺设水平钢筋网.图5,表1,参4.
Based on the analysis of mechanical properties of high embankment, numerical analysis is made on the distribution of stresses and displacements under loading and reinforcement or not, and the aspects of loading and filling construction technology during construction of high embankment are described Quality control and construction safety control of fouling body and its countermeasures.It is pointed out that stratified rolling, pile loading and engineering load are the necessary conditions for high-quality filling and safety construction control, and the layered rolling process should pay attention to different Different displacement characteristics of the site; recommended by the central reinforcement to improve the stress state of the fill body to enhance the stability of high embankment, and laying of horizontal steel mesh at the bottom of the subgrade and the middle.
