“…The key in using FEM to solve the ultimate bearing capacity is how to determine whether the foundation reaches the ultimate destructive state based on the results of finite element calcula tions. There are several types of soil instability criteria as discussed by Du et al (2017). How ever, this study uses the load-displacement curve from the FEM software to determine the ultimate bearing capacity.…”

I have been teaching and researching rock engineering and practicing as a consultant since 1972. I have spent most of that time in underground mining. I have seen significant changes, both evolutionary and radical, in the sector. In this paper, I reflect on some of these changes in mining geomechanical practice. I will also comment on some of the positive and occasionally less positive impacts of these changes. One constant throughout my career is that geomechanical designs will always be fraught with uncertainty. As a result, we will discuss geomechanical design as being, in its essence, a risk management exercise. I will argue that, as impressive as modern numerical analysis techniques are, they do not on their own mitigate design risk; under worst-case scenarios, they make things worse. Empirical and simple models must be used as a check. The paper intends to provoke healthy skepticism in geomechanics practitioners, designers and managers regarding all the aspects of the geomechanical analysis and design process. A failure to recognize the risks in these processes can have catastrophic effects.

“…The load corresponding to the inflection point on the loaddisplacement curve is used as the criterion of critical damage state. At present, many scholars tend to choose this criterion because the load-displacement curve gives the most intuitive reac tion of foundation instability (Du et al, 2017).…”

“…The traditional status quo approach for the value of allowable soil bearing capacity for the crane rental companies is to use the information provided by the client. This approach lacks integration of crane tracks/outriggers/mats, impacting the allowable soil bearing capacity [4], [9]- [12]. The current manuscript utilizes the equations developed by Terzaghi [5], Meyerhof [6], Hansen [7], and Vesic [8] to calculate the soil bearing capacity.…”

The use of modular construction burgeoned mobile cranes' impact on construction sites, which has led to the manufacturing of heavier modules with weights often measured in hundreds of tons. Because of the surge in module weight, mobile cranes are predominant, ensuring adequate ground stability under the lifting equipment since its debacle can have dire repercussions for the workers and the project. The traditional approach is to make use of timber/steel mats for ground stability. Before that, it is crucial to estimate the allowable soil bearing capacity as a prerequisite to reckon the compensation for deficient ground support. The crane rental companies' status quo approach collects this information from the client without incorporating mobile crane track/outrigger surface area (crawler crane track/mat, hydraulic crane outrigger mat). This contribution aims to develop a Visual basic computer application to determine soil's allowable soil bearing capacity for crane work. The developed application consolidates mobile crane footing area and computes allowable soil bearing capacity based on the soil data from a construction site's geotechnical reports. The developed application uses soil bearing capacity theorems (e.g., Terzaghi, Meyerhof, Hansen, and Vesic) for the calculations. The developed application will help practitioners estimate the allowable soil bearing capacity with the crane mat surface area to complement the information received from the clients.

Aiming at the influence of water immersion in the loess stratum on the bearing capacity of the pipe gallery foundation, taking the prefabricated pipe gallery demonstration project in Xiongan New District as the research object, the static penetration test and indoor triaxial test of the foundation bearing layer of the pipe gallery before and after water immersion were carried out. In the experiment, the loss law of loess foundation bearing capacity before and after water immersion was analyzed by using the obtained soil physical index changes. The research results show that the foundation bearing capacity calculated using the static penetration test data before and after immersion are in good agreement with the field plate load test results, and the eigenvalues of the foundation bearing capacity calculated using the shear strength index are higher than the field measured results. According to the results of the static penetration test, the bearing capacity of the foundation after immersion will decrease, but the reduction range is within 4%, and there is a certain loss; the bearing capacity of the foundation before and after immersion calculated according to the shear strength index is reduced by 2.5%. It shows that the bearing capacity of the foundation will be lost to a certain extent after immersion in water, but the loss is small. It is recommended to strengthen drainage measures in the later stage to prevent the foundation from being soaked by rainwater.
