Abstract: A review of Terzaghi's published and unpublished papers and notes made it possible to trace his way from geology over geotechnical engineering to engineering geology. Not only does this reflect his career, it also is the ...

Abstract: Transportation construction projects are often plagued by cost overruns and delays. Applying contingencies and estimating risks at the project level often do not capture the multiple uncertainties in the construction process ...

Abstract: It has been observed in many tunneling projects that surface settlement troughs caused by twin tunnels have a variety of shapes unlike single tunnels, where symmetric surface settlement troughs are usually observed. The ...

Abstract: In this paper a new empirical relation between the unconfined compressive strength of intact rock and the end bearing capacity of drilled shafts in rock is developed. In addition, an analytical relation between rock mass ...

Abstract: The “Decision Aids for Tunneling” are a procedure and computer code that can be used to assess the effect on construction cost and time of geologic/geotechnical uncertainties and uncertainties in the construction process. ...

Abstract: The total construction cost and time of projects are often overrun. It is known that when positive correlations between costs are disregarded, the range of possible total construction costs is underestimated. A model is ...

Abstract: To counteract cost escalation and delays in infrastructure construction, an estimation model has been developed that simulates project uncertainty with probability distributions, correlations, and disruptive events. When ...

Abstract: In this paper, a nonlinear continuum method is developed to predict the load-displacement response of drilled shafts under lateral loading. The method can consider drilled shafts in a continuum consisting of a soil layer ...
