The main aims of this paper are to propose new superior equations and to introduce two novel techniques for TBM performance prediction. First of all, correlations between Rate of Penetration (ROP) and rock mass properties were investigated by means of four simple regression analyses including exponential, polynomial, power and Fourier functions. Th...

Determining footing design parameters is crucial in designing buildings and other geotechnical structures. Bearing capacity and settlement of foundations are two important design parameters that can be determined with the aid of experimental, numerical, and analytical methods. However, estimating the aforementioned parameters using the above-mentio...

This research aimed to investigate the effectiveness of Polyethylene-Terephthalate (PET) as a reinforcement material for sandy soils in enhancing the shear strength. To achieve this, different concentrations of PET were tested, and 118 sets of data were collected. Parameters such as relative density, normal stress in direct shear strength test, and...

In recent years, mine site closure and rehabilitation have emerged as significant global challenges. The escalating number of abandoned mines, exemplified by over 60,000 in Australia in 2017, underscores the urgency. Growing public concerns and governmental focus on environmental issues are now jeopardising sustainable mining practices. This paper...

In recent past years, the implementation of artificial intelligence (AI) techniques in rock characterization is highlighted in the literature. This is attributed to the fact that direct determination of rock engineering properties such as unconfined compressive strength (UCS) is time-consuming, costly, and some times difficult. This study aimed to...

Due to the different challenges in rock sampling and in measuring their thermal conductivity (TC) in the field and laboratory, the determination of the TC of rocks using non-invasive methods is in demand in engineering projects. The relationship between TC and non-destructive tests has not been well-established. An investigation of the most importa...

In today’s constructions, soil weakness in shear and tension is important. Geogrid is a common solution for improving bearing capacity for soil reinforcement with geotechnical problems. In this paper, a numerical study, using the finite element method, the circular footing resting on soil reinforced with geogrid sheets is modeled, and the effect of...

Overcoming the negative effects of unrecyclable materials has become a global concern in the last ten years. One of the unrecyclable materials used to make containers is polyethylene-terephthalate (PT). The use of such materials in enhancing soil has grown in significance. A tree-based classification method for the increase in shear strength brough...

In the past decades, TBM performance analysis takes paramount importance among several project management and underground space technology problems on account of its impact on cost estimation, time planning, efficiency improvement, and other relative issues. The main aim of this paper is to propose new superior equations for TBM performance predict...

Hard rock TBM performance prediction is of great interest to the tunneling community on account of its importance in time and cost risk management of underground projects. Continuous development of new empirical models in recent decades reveals the importance of accurate prediction of this factor in diverse ground and machine conditions. The great...
