Numerical Analysis of Jet Grout Elements for Braced Excavation in Soft Clay

A Comprehensive Review of Sustainable Assessment and Innovation in Jet Grouting Technologies

“…The use of FEM (Finite Element Method) has been extensively documented in the field of jet grouting technology study, with numerous studies [66][67][68][69][70][71][72] using this method to investigate ground movement and structural integrity after intervention. FVM (Finite Volume Method) [28] and FDM (Finite Difference Method) [73] analyses complement this by providing additional perspectives on material dispersion and interaction with the environment.…”

Deterministic and reliability assessment of basal heave stability for braced excavations with jet grout base slab

“…The depth to the hard stratum is assumed to be large. The properties of the JGP (see Table 1) are based on common design values used in Singapore (Ho and Hu 2006). In addition, it is assumed that the wall has enough capacity not to fail under the action of deepseated soil movements.…”

“…Another possible solution is to use a ground improvement technique known as jet grouting prior to excavation (Wen 2005;Ou 2006). The jet grouting process produces a series of short overlapping grout columns to produce a "continuous" base slab (commonly termed as jet grout pile or JGP) below the final excavation level that spans across the entire excavation (Gaba 1990;Hsieh et al 2003;Ho and Hu 2006). Typically, the JGP thickness ranges from 2 m to 4 m. In one particular large excavation (approximately 90 m wide and 240 m long) in Singapore, a 9 m thick JGP slab was used (Wong and Poh 2000).…”

Simulation of cement-improved clay structures with a bonded elasto-plastic model: A practical approach

“…The mechanical behaviour of the treated soil bodies is generally represented with simple models, typically the elastic perfectly plastic Mohr Coulomb model e.g. [15,25]. One characteristic that is poorly represented by that type of models is brittleness of mechanical response, a basic trait of cemented geomaterials both natural and artificial.…”
