6纤维加筋膨润土在大剪切位移下的性状显示文摘通过正应力为20—400kPd下的系列环剪试验,研究了聚丙烯纤维加筋膨润土在大剪切位移下的性状。膨润土和聚丙烯纤维制成初始含水量170%的试样,纤维长12mm或24mm,厚0.023mm,在试样中干重含量为1.5%或3%。纤维在膨润土中随机分布,提高了试样的最大抗剪强度,但当变形继续增大时,加筋土的强度加剧变小,使得纤维加筋膨润土和素膨润土残余强度相似。纤维长度和含量的增加都会提高峰值剪切强度。试验结束后将纤维取出,发现纤维体出现拉长和破坏。Michéle Dal Toé Casagrande Matthew Richard Coop Nilo Cesar Consoli 张杰(译) 2006地基处理2006,17,4:0
7Mechanical behavior of iron ore tailings under standard compression and extension triaxial stress paths显示文摘The disposal of mining tailings has increasingly focused on the use of dry stacks.These structures offer more security since they use filtered and compacted material.Because of the construction method and the heights achieved,the material that compounds the structure can be subjected to different stress paths along the failure plane.The theoretical framework considered in the design of these structures generally is the critical state soil mechanics(CSSM).However,the data in the literature concerning the uniqueness of critical state line(CSL)is still controversial as the soil is subjected to different stress paths.With respect to tailings,this question is even more restricted.This paper studies two tailings with different gradings due to the beneficial processes over extension and compression paths.A series of drained and undrained triaxial tests was conducted over a range of initial densities and stress levels.In the q-p'plane,different critical stress ratio(M)values were obtained for compression and extension stress paths.However,the critical state friction angle is very similar with a slightly higher critical state friction angle for extension tests.Curved stress path dependent CSLs were obtained in the n-lnp0 plane with the extension tests below the CSL defined in compression.Regarding the fines content,the studied tailings presented very similar M and critical state friction angle values.However,the fines content af-fects the volumetric behavior of the studied tailings and the CSLs on the n-lnp0 plane shift downwards with the increasing fines content for compression and extension tests.In relation to dilatancy analysis,the fines content did not present an evident influence on the dilatancy of the materials.However,different values of mean stress ratio N were obtained between compression and extension tests and can corroborate the existence of non-unique CSLs for these materials.Alexia Cindy Wagner João Paulo de Sousa Silva João Vítor de Azambuja Carvalho Ana Luisa Cezar Rissoli Pedro Pazzoto Cacciari Helder Mansur Chaves Hugo Carlos Scheuermann Filho Nilo Cesar Consoli 2023Journal of Rock Mechanics and Geotechnical Engineering2023,15,7:0
