Imaging of Voids Beneath Bridge Bent Using Electrical Resistivity Tomography

In an effort to better understand and define the lateral and vertical extent of shallow water-filled voids beneath a bridge bent (I-44, across Gasconade River), Missouri University of Science & Technology (MS&T) will acquire electrical resistivity tomography (ERT) data along six traverses immediately adjacent to the bent in question. Four of the ERT traverses will be laid out parallel to the river, two on either side of the bridge bent in question. Depending on site access constraints, the other two ERT traverses will be laid out roughly perpendicular or at a skewed angle to the river on either side of the existing bridge bent. The layout may need to change due to site access and potential issues working around the construction at the site. The intent is to use this non-invasive technology to map the lateral and vertical extent of the water-filled voids so that appropriate mitigation plans can be developed.
