Robertson et al (1986) and Robertson (1990) stressed that the CPT-based charts were predictive of Soil Behavior Type (SBT), since the cone responds to the in-situ mechani-cal behavior of …

2016年7月14日 · CPT-based SBTn chart suggested by Robertson (1990) and updated by Robertson (2009). [Colour online.] Proposed Q tn-I G chart to identify soils with microstructure. …

Robertson (1990) suggested two charts based on either Q t -F r and Q t -B q but recommended that the Q t -F r chart (illustrated in Fig. 2) was generally more reliable, since the CPT …

Robertson chart (Robertson 1990) for soil classification based on normalized CPTU data. This paper presents an application of the Bayesian Mixture Analysis (BMA) to deal with the …

1989 Several charts exist for evaluating soil type from &ctric cone penetration test (CpT) data. A new system is propowd based on normahzed CPT data. The new chans are based on …

The soil behavior type index can be thought of as a representative value that combines Qt and Fr to produce concentric circles delineating Robertson’s 1990 SBT chart zones. Ic expresses the …

Twelve ´soil behaviour type` (SBT) zones were proposed by Robertson et al. (1986) and nine (SBTn) by Robertson (1990). Later, Robertson (2010) updated the early Robertson et al.´s …

A popular CPT soil behavior chart based on normalized CPT data is that first proposed by Robertson (1990) and shown in Figure 23. The linear normalization suggested by Wroth …

Robertson et al (1986) and Robertson (1990) stressed that the CPT-based charts were predictive of soil behavior, and suggested the term ‘soil behavior type’ (SBT), because the cone …

The objective of this paper is to present an update to the Robertson (1990, 2009) and Schneider et al. (2008) CPT-based SBT classification system with behaviour-based descriptions for each …
