In this paper , thoroughly discussed are construction technology and quality control of high - filled embankment based on the joint research project , research on construction technology and quality control of high - filled embankment , by guangxi highway management bureau and college of civil engineering , hunan university 本文以广西壮族自治区公路管理局和湖南大学土木工程学院联合承担的科研项目“高路堤施工技术与质量控制研究”为依托,深入研究了高填石路堤施工技术及质量控制技术。
The reference values of strength parameters of the grounds and rock - fillers of the high rock - filled embankment on liuzhai - shuien highway in guangxi are obtained in this paper by synthetically analyzing the construction technology at home and abroad and indoor rock tests . by comparing the analysis method of settlement laws and thoroughly analyzing the datum of the embankment settlements of liuzhai - shuiren highway from the whole cons truction period , a new method generated from expectation technology to analyze the embankment settlement laws , " compete " growth curve , is presented in this paper and the result tallies with the observation data . for there are shortcomings in indoor rock tests , in this paper by combining finite element method with duncan - chang nonlinear constitutive model and composite method , a method for back analysis of the strength parameters of rock fillers is presented with a corresponding program , which has been successfully applied 通过对国内外已有高填石路堤修筑资料的综合分析及室内岩石试验,获得了寨任二级公路高填石路堤地基及填料强度参数的参考值;通过对路堤沉降发展规律现有分析方法的比较及对广西寨任二级公路高填石路堤修筑工程中的沉降全过程观测资料深入分析,运用预测技术,提出了路基及路堤沉降发展规律分析的“龚帕斯”成长曲线分析方法;针对室内岩石试验的局限,运用有限元技术,结合邓肯一张非线性本构模型和复形调优法,提出了高填石路堤填石料强度参数的反演方法,开发了相应的反演分析程序,并成功地反演了广西寨任二级公路高路堤填石料的强度参数值。
Based on the analysis of the experiment on ground consolidation by high - energy dynamic compaction in the coal yard of kemen no . 10 & no . 11 berths in luoyuan bay of fuzhou port . , it is concluded that high - energy dynamic compaction applied for thick stone - filled foundation has such advantages as obvious consolidation effect , simple technology and low cost 摘要通过福州港罗源湾港区可门作业区10 (上标# ) 、 11 (上标# )泊位煤堆场高能量强夯加固地基试验分析,证明高能量强夯法用于沿海厚填石(土)场地进行地基处理效果明显、工艺简单、费用较低。
Based on the routine test of rockfill , built indoor model experiment of it under the process of vibration compaction , the flat panel vibration machine was used to vibrate and compact the layered rockfill , the level instrument was used to observe the settlement of rockfill after vibration compaction , dynamical soil manometer was used to observe the pressure variety in the rockfill layer 摘要在进行填石料常规土工试验的基础上,建立填石料振动压实的室内试验模型,采用平板振动器对填石料分层进行振动压实,利用水准仪观测填石料在振动压实中的沉降量,利用动土压力计观测填石层内的压力变化。
With the rapid development of the constructions in mountain areas , high - fill embankments , especially high - rock filled ones will be widely applied . of all the questions during the construction of such embankments , such ones are needed first to be solved as finding economical construction ways and easy - to use quality control methods 随着山区高等级公路的迅速发展,高路堤特别是高填石路堤已成为我国山区高等级公路建设中无法回避的一种路堤结构形式,在高填石路堤修筑所面临的问题中,填石路堤的经济合理的施工技术、简便易行的质量控制方法等方面是急需解决的最关键的问题。
