Details of this methodology, including a detailed desk study, computational geomechanics, a well-targeted ground investigation, void remediation and real-time foundation monitoring, are discussed in this paper. A key project challenge was the presence of ancient shallow coal workings and shafts...

A numerical model of the highway widening is established based on the actual project, and the hypothesis is verified...

... in the following sections. A typical problem is a retaining wall above track level (Figure 3 (a)). The absence of ballast typically decreases the bearing capacity of the foundation by 10–20%, and reduces available passive pressure significantly. The shear and moment in the wall typically increase by 1–2...
