The shear strength indexes of and c were obtained for these two embankments , and they demonstrated the reliability of thrust and sliding equilibrium method used to analyze the stability of embankment 在计算过程中提出4点基本假设,经过现场试验数据计算分析,论证了假设的成立和推滑平衡分析法应用于填石路堤的正确性,并通过比较得出灰岩作为材料使填石路堤边坡更为稳定的结论。
It is expounded that the main points of design , construction characteristics and precautions of a phc pipe pile when it is used for a site of backfilled stone layer , according to the design of phc pipe piles for an industrial mill building , which may be a reference for the same trade 摘要结合某工业厂房的phc管桩设计,阐述了在有填石层特定场地条件下的设计要点,施工工艺特点和注意事项,可供同行借鉴参考。
With the rapid development of the constructions in western china , the research on the design and building technology , the quality control and the evaluation parameters of high rock - filled embankment has been one of the key technologies in highway building in mountainous areas 随着我国西部建设的高速发展,高填石路堤的设计、施工技术及其质量控制方法和评价指标的研究已成为山区高等级公路面临的关键技术之一。
The results show that , the settlement of rockfill increases with vibration compaction times adds , its density enhances , when the settlement of rockfill reaches some extent , it decreases instead increases with the vibration compaction increases , moreover the density reduces 试验结果表明:随着振动压实遍数的增加,填石层的沉降增加,密实度提高,但当沉降达到一定值以后,随着振动压实遍数的增加,填石层的沉降不增加反而减少,密实度降低。
In this paper , first discussed are the corresponding results in highway and dam constructions and the engineering characters of rock - fills are deeply analyzed , especially the relationships between gradation , strength and maximum dry density , long - term stability of fillers including earth - fillers and rock - fillers and some conclusions of use are drawn . by in - situ tests and researches on compacting mechanism of high - filled rock embankments , effecting factors on compaction , construction technology and shock compacting technology , obtained in this paper are the compacting technology of high - filled rock embankment and the optimal parameters of rolling compaction . by deeply research on the theory and methods of quality control of high - filled embankment , settled are the questions as quality detection method and control standard of high - filled rock embankment 本文首先总结和分析了国内外公路和坝工行业已有的相关成果,深入探讨了填石料的工程性质与最大干密度、长期稳定性等之间的关系,得到了一些有益的结论;通过现场试验路堤的试验和对高填石路堤压实机理、填石路堤压实效果影响因素、施工工艺和冲击压实技术等研究,解决高填石路堤压实工艺和最优碾压参数控制等技术问题;通过深入研究填石路堤压实质量控制原理和方法,解决高填石路堤压实质量检测方法和控制标准技术难题;解决高填石路堤沉降观测技术问题,并根据沉降观测结果研究高填石路堤地基和路堤沉降变化规律,得到了能预测沉降变化规律的“龚帕斯”成长曲线预测模型;根据工程实际,深入研究了边坡稳定性的影响因素,得到了有益的结论。
