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 this ...

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 of ...

Impact of lowered laboratory compaction rate on strength properties of asphalt mixtures

Highly important issue related to good pavement quality and job performance is in case of asphalt mixtures the compaction rate of asphalt layers. Compaction rate is a factor which has very significant impact on the durability, strength properties, resistance to cracking, etc., of asphalt pavements. Even though the compaction rate influences the lifespan of a pavement, it is very ...

Lateral capacity of pile with grouted upper soil: field test and numerical simulation

Laterally loaded piles may entail large deformation under some circumstances such as ship impact, earthquake and long-term horizontal thrust of arch bridges, etc. The arch bridges are especially sensitive to horizontal displacement of foundation. Lateral load test was performed on a full-scale pile in virgin soil and pile with post-grouted soil around pile. Further numerical ...

The main purpose of this paper is to determine the integral equation formulation of the displacement vector at any point within the problem domain of unsaturated expansive soils. The displacement values could be calculated if boundary conditions are prescribed as well as initial stresses and the suction distributions within the domain.

Finite element slope stability analysis of Souk Tleta dam by shear strength reduction technique

Slope stability analysis of earth dam is very important to ascertain the stability of the structure. The stability of earth dam depends on its geometry, components materials, water pressure and the forces to which it is subjected. Souk Tleta earth dam, currently under construction, is located on Bougdoura River, in north Algeria. The main purpose of the dam is to store surface ...

Performance of sand-emulsion mixes under the effect of field and laboratory environmental conditions

Because of its high availability, sand is one of the most important construction materials in Egypt. The main objective of this paper is to study the performance of sand-emulsion mixes under the effect of field and laboratory environmental conditions. Laboratory simulation of environmental conditions could be achieved by subjecting sand-emulsion specimens to wet-dry cycles through ...

Effect of geogrid reinforcement on flexible pavements

Effectiveness of geogrids in flexible pavement reinforcement was investigated throughout laboratory testing and finite-element analysis (FEA). The laboratory testing involved routine material characterization, resilient modulus testing, and five pavement prototype sections. These sections consisted of a 5 cm asphalt concrete (AC) layer, 15 cm granular base layer, and a 30 cm clay ...

River embankment strengthening by non-metallic nails: overview on a permanent soil nailing for flood protection

River embankments, levees, and coastal dikes are often subject to important remediation and ground improvement works. Such actions will become increasingly important in the future: we have to consider the strategic position of such structures along urban shorelines and waterways together with the ongoing sea-level rising process. In this paper, the application of a permanent soil ...

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 ...

Utilization of weathered rock mass as the China Three Gorges Project Dam foundation

The utilization of the weathered rock mass in the Three Gorges Dam Area is one of the key geotechnical issues for the China Three Gorges Project (CTGP) construction. Engineering geological investigations and tests had been carried out to study the physical, chemical, mineral and mechanical properties and distribution characteristics in detail for more than 30 years. The ...

Behaviour of model footing resting on sand reinforced with number of layers of coir geotextile

Several methods of ground improvement techniques were developed and tried for stabilizing weak soils. The technique of reinforcing the soil becomes one of the important methods. The performance of granular soils which are strong in compression and shear, but weak in tension can be substantially improved by introducing reinforcing element in the direction of tensile strain. Compared ...

Risk analysis-driven design in tunnelling: the state-of-the-art, learnt from past experiences, and horizon for future development

Risk management became an integral part of most underground construction projects during the late 1990s, also considering the increasing requests in term of safety, and environmental and socio-economic sustainability coming from citizens, owners, lenders, and insurers. The application of risk management procedures, today widely applied, ensures that design’s team efforts can be ...

A convergence criterion for water conveyance tunnels

One of the important methods used by tunnel construction engineers to examine the design, construction safety factor, and tunnel boring procedures is convergence measurement.
