“…Lodder et al (2012) and Van Eekelen et al (2012b, Chapter 3 of this thesis) suggested using a modified value for the subgrade reaction k to take into account all subsoil 17 underneath the entire GR. This suggestion is in line with the work of Jones et al (2010), Halvordson et al (2010), Plaut et al (2010) and Filz et al (2012). Van Eekelen et al (2013, Chapter 4 of this thesis) recommend using the CA model, an inverse triangular load distribution and taking into account all soil support underneath the GR between the piles.…”

“…Table 5.13 gives an overview of the analytical models considered in this paper. Strip subsoil support is considered to be unrealistic , Van Eekelen et al (2012b, Chapter 3 of this thesis), Filz et al (2012)) and is therefore considered only in a limited number of cases for the purposes of comparison.…”

“…This is considered to be unrealistic since there is no reason why only part of the subsoil should contribute to the support (Lodder et al, 2012, Chapter 3.4.1;Filz et al, 2012). Subsoil support was therefore extended to 'all subsoil' between the pile caps.…”

“…The rigid arch models include Scandinavian models such as Carlsson (1987), Rogbeck et al (1998, modified by Van Eekelen et al, 2003), Svanø et al (2000), the enhanced arch model described in, for example, Collin (2004), the design method of the Public Work Research Centre in Japan (2000, discussed in Eski ar et al , 2012). The models that consider the behaviour of the separate mechanical elements and match their boundaries are described in, for example, Filz et al (2012), Deb (2010), Deb and Mohapatra (2013) and Zhang et al (2012). The present paper focuses on the last family of arching models: limit equilibrium models.…”

Summary Railroad track problems have been exacerbated by the continuous increase in freight loads and train traffic. The need to implement soil improvement technique in a relatively short window‐time (ie, to minimize train‐traffic disruption) is a key aspect to be considered when adopting a convenient remedial solution to control settlements in railroads constructed on problematic subgrades. Rigid inclusions are selected in this paper because they are reliable solutions relatively easy to implement. Furthermore, they can be used in different ground conditions and are suitable for short construction times (eg, do not require a curing time, as in grouting methods). Typical (analytical) methods for the design of rigid inclusions are adopted in this paper to define an optimal distribution of piles for the case of existing railroads. The selected layout is then analyzed in detail by means of a 3‐D dynamic finite element simulator using both, elastoplastic and elastic models. The performance of rigid inclusions is studied considering different operational scenarios, with dynamic and static loads, as well as involving subgrades with different plasticity index values. It is found that the predictions from the analytical design methods for rigid inclusion tend to be unconservative when compared against the finite element results. As for the numerical solutions, the most unfavorable stress condition is associated with the dynamic elastoplastic finite element solution. It is estimated that the rigid inclusions will contribute to a reduction in the ground settlements of around 15% to 20%, depending on the subgrade plasticity index.
