Abstract Automating earth-moving tasks has the potential to resolve labour-shortage, allow for unseen designs and foster sustainability through using on-site materials. In this interdisciplinary project involving robotics landscape architecture, we combine our previous work on autonomous excavation of free-form shapes, dynamic design terrain modelling tools into a robotic system. It tightly con...

Development of cities and villages, agricultural farms and industrial regions in abutment and/or in the course of streams and rivers or in prone flood lands has been caused more notations in hydrology problems and city planning topics. In order to protection of cities against of flood damages, embankment construction is a desired and scientific method. The cities that located in arid zones may ...

A computational methodology dedicated to embankment dam performance assessment has been designed and implemented. The model’s inputs are the whole set of available information and data: visual observations, monitoring measurements, calculated data and documents related to design and construction processes. Firstly, a formal grid is proposed to structure the inputs. It is composed of six fields:...

Abstract—Cavities are frequently found beneath conduits on pile foundations in old embankments. Cavity reduces seepage length significantly and consequently causes piping failure of embankments. Case studies of embankment failures indicate that the relative settlement between ground and pile supported-concrete conduit was the main reason of the cavity. In this paper, an attempt to simulate the ...

Strong cross-winds may overturn trains, so an understanding of the fluid mechanics is important. To facilitate the proper estimation of the probability of a train overturning, accurate data for the aerodynamic rolling moment about the lee rail is essential. (Of course, many other parameters are required.) The flow of a turbulent cross-wind over a train moving across an embankment is complex, an...

Application of micro-piles to stabilize unstable slopes has been widely considered in recent years. A micro-pile is a small-diameter (typically less than 300 mm), drilled, and grouted as non-displacement pile that is typically reinforced. The main objective of this study is to evaluate the influence of the micro-pile group on increasing safety factor as well as finding the optimum position of m...

The evolutions of practices of seismic slope stability analysis of earth embankment/dam are discussed in this paper. The basic concepts of various methods, salient features, advantages and limitations of each of them are elucidate. Methods for both stability analysis and deformation calculation are presented. Methods for calculation of deformation of post liquefaction stage are also briefed.

Forecasting dam behaviour is of paramount importance to avoid collapses. It consists of detecting and controlling deterioration mechanisms. This paper sets out to propose a multi model methodology to model complex dynamic systems, such as dams. It defines three models based on expert knowledge: a structural model, a functional model and a behavioural model. They are developed from the stories o...

A rise in the shallow unconfined groundwater at a site in Australia is causing water logging of the underground facility in the affected area. Realizing this problem, a study was conducted to identify the source of water that is causing the rise and to develop an implementation and operation plan of the mitigation (dewatering system). Modelling was undertaken using MODFLOW-SURFACT code, within ...
