| 摘 要： | 针对风化岩体仍无理想的定量分带方法这一研究现状与工程建筑需要的矛盾,提出了对能够检测工程环境岩体风化程度的各种物理力学、矿物学和声学指标进行方差分析和特殊的“动态方差分析”方法,可对岩体风化带的划分进行定量评价,达到某一试验结果下的最佳分带效果。还结合应用实例讨论了不同地质条件下分带计算过程的相应变化和应用效果。最后指出,工程岩体分类亦可借鉴本文的研究方法。

| Abstract: | This article had summarized the methods currently used for dividing the weathering rock masses into different zone.The main problem in dividing weathering rock mass is to make it fit the enginnering demand. But the present methods are failed in doing so, especially there is not a theoretically sound, accurate and quantitation method; what we have had are too artificial. This article had advanced a way to test the weathering rock mass through the application of variance analysis and dynamic variance analysis to the mechanicalmineral composition and acoustical properties of the weathering rock mass to quarantee a quantitation approach and an optimum evaluation of the problem.In demonstrating this method variations of calculation responding to different geological conditions are discussed. Besides, method to over come the interference of changing in rock properting with the testing of weathering rock mass has been put foreward.The example given in this paper shows the effectiveness of this method, and it is hoped that the gradation of engineering rock masses may get some hints from this method. |
