Effect of soil particle and pore orientations on sound velocity

The main purpose of compressing soil dams, highway constructions, bridge abutments and fillings behind retaining walls is to increase the bearing capacity, reduce consolidation settlement and permeability of clayey soils. However, the soil particles and pore orientation could be somehow anisotropic due to a compaction-induced anisotropic structure. Orientations of particles...

Experimental direct shear tests were performed...

Compaction characteristics and strength of BC soil reinforced with untreated and treated coir fibers

Black cotton soils, because of its high swelling and shrinkage characteristics, have been a challenge to geotechnical engineers. Use of natural reinforcing materials in soil such as jute and coir has the advantage that they are available at low cost. Among the natural reinforcing fibers in soil, coir has the greatest tensile strength and retains its property even in wet...

Evaluation of hot mix asphalt made with recycled aggregates from demolition waste (RADW) coated with bitumen emulsion

In the previous researches, the RCA were...

Evaluation of recycled concrete aggregate in asphalt mixes

This paper investigates the feasibility of using recycled concrete aggregate (RCA) as a replacement to the natural aggregates (NAs) in hot mix asphalt (HMA). RCA was collected from two different sources (new concrete cubes used for quality control testing during construction, and old demolished building) to investigate the impact of material degeneration on the engineering...

Ground response analysis and liquefaction hazard assessment for Vishakhapatnam city

Liquefaction is a complex phenomenon where the soil is subjected to high strain levels due to dynamic loading at the time of seismic events, contributing to severe damage and collapse of the structures. The effect of liquefaction can be predicted in three stages, i.e., evaluation of susceptibility, hazard and deformations. Soil susceptibility to liquefaction can be assessed using...

Assessment of liquefaction potential of Guwahati city by probabilistic approaches

This paper presents a probabilistic assessment of the liquefaction potential of Guwahati city, in the northeastern region of India, by using eight probabilistic approaches. Northeastern region of India is one of the six most seismically active regions of the world. The assessment was done for saturated cohesionless deposits. Probabilistic liquefaction assessment is done in terms...

Modeling maximum surface settlement due to EPBM tunneling by various soft computing techniques

There are various methods to predict the settlement caused by shallow tunneling, with each method having particular strengths and weaknesses. However, the most important weakness of common methods is the failure to consider all parameters contributing into the settlement. Nowadays, earth pressure balance machines (EPBMs) are commonly applied for tunneling into soft grounds. In...

Numerical check of the Meyerhof bearing capacity equation for shallow foundations

Most geotechnical design codes and books use the equations of Meyerhof or Terzaghi to calculate shallow foundations. These equations are based on the failure mechanism published by Prandtl for shallow strip foundations. The common idea is that failure of a footing occurs in all cases according to a Prandtl-wedge failure mechanism. To check the failure mechanism and the equations...

Minimizing the use of concrete in tunnels and caverns: comparing NATM and NMT

For many decades, a tunnelling method has been in use which effectively minimizes the use of concrete, which should be one of the goals in our CO2-producing planet. We call the method NMT (Norwegian Method of Tunnelling) and emphasize its ‘single-shell’ characteristics, to distinguish it clearly from double-shell NATM (the so-called New Austrian Tunnelling Method), which is...
