Growth and subsurface development of three sinkholes in Kansas with seismic methods.

<p>Embankment dams comprising broadly graded materials of glacial origin in the impervious core (base soil) and protective filter have in the past been identified as being prone to develop sinkholes more frequent than dams composed of materials of other origin. ...

<p>The occurrence of occasional sinkholes or very large settlements over EPB driven tunnels has been documented on a number of projects. Primary responsibility for avoiding sinkholes must lie with the tunnelling contractor, and the shield manufacturer. Almost ...

This paper employs a case history to describe deployment of new TDR cable and communication technologies to monitor stability. It involves remotely monitoring possible sinkhole-induced deformation near a “land bridge” installed over a recent subsidence event. ...

Even though the model presented in this paper requires further refinement and improvement, FLAC modeling offers a promising approach for the evaluation of geosynthetic reinforcement above sinkholes where strains within the overlying materials is of concern, ...
