| 摘 要： | 软弱夹层是控制岩体稳定性的重要薄层,研究软弱夹层的工程地质特征具有重要的科学意义和实际工程意义。在收集整理国内外相关资料的基础上,首先从定义和分类、形成机制和影响因素、分布特征和规律、工程地质特性和力学特性5个方面对国内软弱夹层和泥化夹层的研究进行总结和概述,然后分析当前研究存在的不足之处,讨论软弱夹层与泥化夹层的区别与联系。研究表明,与原生软弱夹层相比,泥化夹层更薄,工程地质性质更差。最后提出下一步重点研究方向:软弱夹层的泥化演化过程及泥化夹层的演化趋势;软弱夹层的三维空间分布及可视化;软弱夹层的剪切蠕变理论模型,细观损伤破坏动态演变规律,应力松弛特性和动力学特性;软弱夹层与围岩间的接触面及组合岩体的力学特性。

| Abstract: | Weak intercalation is important thin layer and plays an important role in controlling the stability of rock mass.Concerning weak intercalation study have gotten plentiful accomplishment.However,the knowledge of people still has a lot of blank spots,the problem needs that still have a lot of aspects are going deep into a discuss.Furthmore,engineering geology problems induced by weak intercalation are still common.Therefore,it is of important engineering significance and scientific significance for carry out the study of weak intercalation.Based on the collection and review of the domestic and foreign literatures related to the weak intercalation,firstly,the paper reviewed the definition and classification,formation mechanism and influencing factor,spatial distribution,engineering geological characteristics and mechanical properties of weak intercalation.Secondly,the existing problems in the studies of the engineering geological properties of weak intercalation were analyzed and the differences and relationship between weak intercalation and siltized intercalation were discussed.Results show that the thickness of siltized intercalation is thinner and the engineering geological properties of siltized intercalation are weaker as compared to primary weak intercalation.Finally,on the basis,this paper also puts forward the key directions of the studies about the issues.They include the argilization process of weak intercalation and the evolution trend of siltized intercalation,the three-dimensional spatial distribution and visualization of the weak intercalation,the shear creep model,meso-damage and failure process,stress relaxation and dynamic properties of weak intercalation,the mechanical properties of combined weak intercalation and surrounding rock and interface between weak intercalation and surrounding rock. |
