Cyclic loading on civil structures can lead to a reduction of strength and stiffness in the loaded materials. The lifespan of many cyclically loaded structures such as wind turbines, high-speed train tracks and bridges strongly depends on the foundation. The soils and rocks in the foundation can be subjected to cyclic loads from natural and human source...
View ArticleAccording to the characteristics of rock bolts in mining engineering, a mechanical model for not fully grouted rock bolt is presented to obtain the expression of shear displacement, the axial force and the shear stress along the anchor section. On these bases, the effect of the length of anchor section on the performance of rock mass and the effect of t...
View ArticleMunicipal solid waste (MSW) settlement can be understood as volume reduction of the waste mass disposed in a landfill. Such phenomenon is mainly the result of organic matter degradation. Settlement can also be generated by MSW distortions, particle rearrengements, and other factors. These factors can be accurately analyzed if studied in an MSW experimen...
View ArticleThis paper presents a new approach to stability analysis of multi-face slopes, employing the concept of restricted daylight envelope. The methodology was applied to the back analysis of a real case of a curved, convex slope in metamorphic slates in Madrid, Spain. The Barton & Bandis (1990) criterion was employed for the field estimation of shear...
