Abstract
CH2M HILL is providing engineering, procurement, and construction services for a power plant project in Utah. Before beginning construction on the power plant, geotechnical studies were performed to characterize the subsurface conditions for the anticipated settlement and to determine a ground improvement method to accelerate the construction period. Ground improvement with wick drains and surcharge fill placement was carried out to improve the soft soil conditions at the project site. Settlement monitoring instrumentations were installed before placing structural fill and surcharge fill. An extensive settlement monitoring program was also implemented inside and around the perimeter of the project site to monitor the settlement impact to adjacent facilities due to structure load and surcharge fill placement. The monitoring period was extended even after surcharge fill removal to observe the rebounding behavior of the foundation soil. This paper presents the challenging site conditions, such as soft soil, the design optimization implemented to accelerate the settlement period, and the comparison between predicted and measured settlement at the project site. This paper also presents finite element simulation of ground deformation and rebound behaviors observed during the surcharge loading and unloading stages.

Ground Improvement and Settlement Monitoring Program For A Power Plant Project

CH2M HILL is providing engineering, procurement, and construction services for a power plant project in Utah.

Settlement monitoring instrumentations were installed before placing structural fill and surcharge fill. An extensive settlement monitoring program was also implemented inside and around the perimeter of the project site to monitor the settlement impact to adjacent facilities due to structure load and surcharge fill placement.
