What geotechnical software is used to analyze relatively rigid walls used for supporting the soil mass laterally?
Geo5 GEO5 is a geotechnical software suite developed by Fine s.r.o. (Czech Republic). First programs were written by Jiri Laurin in 1989 in cooperation with the Faculty of Civil Engineering of CTU in Prague. The software is used in the field of geotechnical engineering to analyze slope stability, shoring excavations structures, retaining walls, foundations (piles, spread footing or mats) and tunnels.
Bailer (hydrogeology) A bailer in hydrogeology is a hollow tube used to retrieve groundwater samples from monitoring wells. Groundwater monitoring wells are drilled in areas where there are underground storage tanks or where there is environmental remediation occurring. The wells are typically built out of PVC casing which is slotted to allow groundwater to flow freely through the well. Bailers are tied to a piece of rope (usually made from nylon or polypropylene) or a piece of wire (composed of Teflon or stainless steel) and lowered into the water column. Once lowered, the bailer uses a simple ball check valve to seal at the bottom in order to pull up a sample of the groundwater table. Bailers can be disposable or reusable, and they are made out of polyethylene, PVC, FEP or stainless steel.
