As a ground improvement technique, the new method composed by cylindrical cavity expansion (CCE) combined with vertical drains (VD) greatly accelerates consolidation of soft soil. In fact, applies radial displacement in Excess pore pressures will be consequently generated and process occur at vicinity wall. The dissipation excess can enhanced presence VD installed distance rd from center cavity...

Preloading with a surcharge is today commonly used together prefabricated vertical drains for embankment construction on clayey soil to accelerate primary consolidation and increase strength. Because of considerable uncertainty related mainly the rate consolidation, there need account this in drain design ensure quality construction. Addressing issue, paper presents novel probabilistic methodol...
