Abstract

This chapter delves into the effectiveness of the Deep Mixing Method (DMM) for ground improvement, particularly in Vietnam's challenging soft clay conditions. The study presents a detailed methodology involving soil investigation, design specifications, and monitoring results from a full-scale field test. It compares DMM with conventional methods like prefabricated vertical drains (PVD), focusing on stress distribution, settlements, and lateral movements. The research employs finite element simulations using Plaxis software to evaluate and back-analyze the DMM method. Key findings include significantly lower stresses on piles and subsoil compared to theoretical calculations, enhanced overall stability, and a remarkable reduction in lateral displacement by over 95% compared to PVD preloading. The study concludes that DMM is a highly effective and safe method for ground improvement, offering superior performance in stability and settlement control.
