Evaluation of Undrained Shear Strength of Soils from Field Penetration Tests

Correlation between Engineering Properties of Bangkok Clay and Penetration Resistance of Screw Driving Sounding (SDS)

“…1482 Correlation between Engineering Properties of Bangkok Clay and Penetration Resistance of Screw Driving Sounding (SDS) There exist several empirical equations which correlate the penetration resistance of SWS with other soil properties such as SPT-N, and uniaxial compressive strength [19][20][21]. Several other studies on SWS are equally significant [1,2,22]. The SWS field technique, however, has many limitations.…”

Influence of state and compressibility on liquefied strength of sands

“…250 Figure 2 shows the decrease of s u (critical)/σ' nc with increasing ψ cs obtained from Equation [6] for 251 some of the sands presented in Table 1. Laboratory data from TxC tests on the same sands 252 (Castro 1969;Dennis 1988;Been et al 1991;Tsukamoto et al 2009) are also included in this 253 figure. The comparison demonstrates the ability of the critical state approach (Eq.…”

On the Possibility of Testing Miocene Clay from Cracow Area using Weight Sounding Test (WST)

“…The relation stated by Inada [9], subject to various kinds of modifications [18], [37], [34], has been used for interpretation of results since the early 1960's. The probe was used, among others, in Turkey [34], Iran [7], [31], India [32], Sumatra [17] and Japan [13], [15], [28], [33], [35], and more recently in New Zealand, in conjunction with the strong earthquake which struck the country in 2010 [2], [3], [29], [36]. Despite the fact that the probe has already been in use for almost 100 years, no standard data interpretation rules have been developed so far (except for a small group of non-cohesive soils) [25].…”
