When a suitable foundation has to be designed for a superstructure, the foundation engineer typically follows a decision-making process in selecting the optimum type of foundation. The flowchart shown in Figure 12.1 illustrates the important steps of that decision process, which is based on the principle that cost-effective alternatives must be sought first before considering relatively costly foundation alternatives. It is seen that, in keeping with the decision sequence advocated in Figure 12.1, one must consider applicable site specific techniques for improvement of soft ground conditions, before resorting to deep foundations.
This chapter gives an overview of techniques that are commonly used by specialty contractors in the United States to improve the performance of the ground in situ. Not included are less specialized methods of ground improvement such as surface compaction with vibratory rollers or sheep foot type compactors, or methods that involve the placement of geotextile or geogrid materials in soil fill as it is placed. The techniques are divided in three categories of Compaction, Reinforcement and fixation.
