“…Chai et al (1995) successfully extended the analysis by Hird et al (1992) to include the effect of well resistance and clogging. In this approach, the discharge capacity of the drain in plane strain (q wp ) for matching the average degree of horizontal consolidation is given by q wp ϭ (28)…”

In this chapter, a two-demensional plane strain solution is adopted for the embankment analysis, which includes the effects of smear zone caused by mandrel driven vertical drains. The equivalent (transformed) permeability coefficients are incorporated in finite element codes, employing modified Cam-clay theory. Selected numerical studies have been carried out to study the effect of embankment slope, construction rate, and drain spacing on the failure of the soft clay foundation. Finally, the observed and predicted performances of well-instrumented full-scale trial embankments built on soft Malaysian marine clay have been discussed in detail. The predicted results agree with the field measurements.

“…During the improvement process, the concerning problem is the settlement during/after the improvement. Numerical calculation is the most common method to predict the settlement [1][2][3][4]. In this paper, the settlement of the ground is numerically calculated by regarding the embankment as equivalent load.…”

Abstract. In order to help the engineer to understand the variation inside the ground before and after the failure of the embankment, to avoid the accident, the surcharge preloading with plastic vertical drains is carried out numerically. The loading rate is accelerated artificially to analyze the variation of the settlement, horizontal displacement, excess pore pressure before and after the failure of the embankment. The results can be used to analyze the measured datum to evaluate the stability of the embankment of the slope.
