Electrokinetic geosynthetic (EKG) strengthening of slopes is a multi-component treatment method which includes dewatering by electro-osmosis; reinforcement; drainage and soil modification.
In this paper, behaviour of a single pile subjected to excavation induced ground movements is analysed using the finite element method, which has the ability to simulate the construction sequence comprising soil excavation, deformations due to dewatering within the excavation and installation of struts.
Metro station constructions are mostly taking pit dewatering measures, while the dewatering of aquifer may cause soil layer compression, land subsidence, foundation's deformation, cracking and tilting of the buildings, and so on.
By the end of the final growing season, the Salix nigra (0.161 g water/g soil) and S. pectinata (18.4 g water/g soil) were able to dewater the sediments without negative impacts on the plants and are recommended for dewatering applications.
The success of dewatering FCPW is the key to emplacement of dewatered FCPW.
The TJPA, said Millennium spokesman PJ Johnston, has engaged in "five years of dewatering [that] has severely dropped the water table beneath our building, causing the soil to compress more than normal, resulting in the building settling beyond what could have been predicted".
When permeable geosynthetic tubes are used for dewatering of waste sludge or construction of dikes or embankments, the tubes have to be inflated using sludge or soil slurry several times.
Since the grouting platform was located on the mat foundation in the basement of underground parking and was under the groundwater table, a series of dewatering wells were installed before the 177 columns were constructed to prevent intrusion of the groundwater flowing upward from sandy soil to basement through grouting hole during wash boring and grouting stages from happening.
Cement pads there would aid in dewatering.
"Dewatering" is another standard construction practice for excavations.
