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。 -

( 2 ) irrigating with less water, only when the quantity of irrigating water in a puddle is more than 4000m1, it can spread into 20cm depth where the crop roots are gathered. otherwise, it is hard for the crops to absorb the irrigating water, and the irrigating water is wasting.
