Abstract An FDM-REV-DEM interface coupling method was proposed based on the concept
of the representative elementary volume (REV). The coupling method was applied to the …

The time-consuming and less objectivity are the main problems of conventional
micromechanical parameters calibration method of Particle Flow Code simulations. Thus …

With the aim of the drilling and blasting in underground space, there are problems of poor
tunnel formation, large crushing and loosening area, difficult support, low driving efficiency …

Empirical based approaches play an important role in tunnel excavation and support system
design. These approaches are considered to be very effective in optimising the process of …

In order to study the applicability of high-pressure gas expansion rock-cracking technology
in hard rock tunnel near historic sites, theoretical analysis, field tests as well as vibration …

A cutting-splitting method is developed as a mechanized excavation for rock slope and
tunnelling. The technique has two procedures. The first step is the rock cutting as designed …

Among influence factors of slope stability, rainfall is the most triggering factor. When
rainwater flows through the slip surface, it will cause slope movement. This paper studies the …

Kestabilan lereng dipengaruhi banyak faktor salah satunya adalah infiltrasi hujan. Hujan
yang terinfiltrasi ke dalam lereng akan menambah berat tanah, dan tekanan air pori, serta …

To accommodate traffic volume on roads due to ever-increasing population growth, the
widening of highways and motorways is in high demand. Nevertheless, the widening of …
