Various geotechnical engineering methods can be used for ground improvement, including reinforcement geosynthetics such as geocells and geogrids, which disperse loads over a larger area, increasing the soil's load-bearing capacity. Through these methods, geotechnical engineers can reduce direct and long-term costs. [12]
This method of ground improvement is also called vibro replacement. Such techniques increase the load bearing capacity and drainage of the soil while reducing settlement and liquefaction potential. Stone columns are made across the area to be improved in a triangular or rectangular grid pattern.
Deep cement mixing (DCM) is a geotechnical engineering deep foundation ground improvement technique where a binder material, typically cement, is injected into the ground for ground stabilisation and land reclamation. The technique can also be used for containing contaminants and water cut-off. [1]
Soil stabilization is a general term for any physical, chemical, mechanical, biological, or combined method of changing a natural soil to meet an engineering purpose. [1] Improvements include increasing the weight-bearing capabilities, tensile strength, and overall performance of unstable subsoils , sands, and waste materials in order to ...
Soil nails were used to stabilize an 18 metres (59 ft) high slope consisting of sandy soil. This method proved to be more cost-effective, while at the same time cut down the construction time when compared to other conventional support methods. [4]: 23 Germany was the next country to investigate soil nailing.
Dynamic compaction is a method that is used to increase the density of soils when certain subsurface constraints make other methods of soil compaction inappropriate. The process involves dropping a heavy weight repeatedly on the ground at regularly spaced points, usually laid out in a systematic fashion such as a grid.
This process results in heat transfer from the ground to the air and keeps the ground in a permanent frozen state. [ 6 ] Hani and Evirgen (2023) introduced a new method for sampling granular soils without disturbing their natural state; they suggest using artificial ground freezing, a ground enhancement technique, as an on-site option for deep ...
Vacuum consolidation (or vacuum preloading) is a soft soil improvement method that has been successfully used by geotechnical engineers and specialists of ground improvement companies in countries such as Australia, China, Korea, Thailand and France for soil improvement or land reclamation. [1]
