By the large quantity of indoor and field soil mechanics test, this paper investigated physics and mechanics property of xigeda stratum and xigeda compounding filling, profoundly and systematically studied on shearing strength, cbr ( including indoor cbr and field cbr ) and intensity feature of xigeda compounding filling. the new achievement and cognition as follows : ( 1 ) cbr value is decided by moisture content and mudstone content of xigeda compounding filling. the filling material can satisfy minimum intensity standard of express highway when mudstone content is less than some fixed value, ( 2 ) this paper established field cbr standard value which can synthetically evaluate the filling material nature and field compaction degree. ( 3 ) the optimal compacting mean of xigeda compounding filling is hard oscillation first and weak oscillation later, not traditional way which is weak oscillation first and hard oscillation later. ( 4 ) this paper put forward the conception of optimum moisture content in construction different from optimum moisture content of indoor impaction
本文以昔格達填料強度特徵為研究對象，通過大量的室內及現場試驗，從昔格達地層巖組的物理力學性質、昔格達填料的物理性質入手，對昔格達填料的抗剪強度、室內承載比及現場承載比特徵進行了較系統地研究，獲得了如下認識及進展：昔格達混合填料承載比值受填料含水量及其中泥巖含量的影響，當泥巖含量小於一定值時，昔格達混合填料具有較高的承載比值，能夠滿足高速公路對填料的最低強度要求；建立了綜合評判昔格達填料性能及現場壓實效果的現場承載比（ cbr ）標準；對于昔格達填料而言，最佳的碾壓方式為先強振后弱振而不是傳統的先弱振后強振；提出了與室內擊實最優含水量相區別的施工最佳含水量的概念。 -
The results show that, after being improved by lime, the high liquid limit soil can be used as subgrade filling of expressway as its liquid limit and plastic index being reduced, the dilatability decreased and the value of cbr increased remarkably
研究結果表明，經石灰改性處理的高液限土，液限與塑性指數均降低，膨脹性顯著減弱， cbr大幅提升，可用作高等級公路的路基填料。 -
Considering that the way to gain standard maximum dry density value of xigeda filling is complex, this paper suggests adopt means combining field cbr test and compactness measuring to control construction quality
鑒于昔格達混合填料標準最大幹密度取值的復雜性，建議採用現場承載比與壓實度檢測相結合的辦法進行現場施工質量控制。 -
After contrasting and analyzing the main design parameters " test methods of laboratory and field outside, it sets up the correlativities between the field bearing plate modulus and other parameters such as design dynamic modulus, benkleman bean static deflection, field cbr value, consistency and density. by means of laboratory experiment, it assays the influence of the consistency on laboratory bearing plate modulus and laboratory cbr values, and establishes the relationships between laboratory and field values. combined with the project, a more logical sub - grade quality test standard is put forward
通過對路基現場檢測不同方法的對比分析，建立了設計動模量、貝克曼梁靜彎沉、現場cbr 、稠度和壓實度與現場承載板模量的關系；通過室內試驗，分析了稠度對室內承載板、室內cbr的影響，並建立了室內外模量間的關系；在此基礎上，結合工程實際，對不同檢測方法進行了評價，提出了較為合理的路基施工質量檢測標準。
