| Abstract | A brief review of ground improvement techniques for road embankments in Bangkok area is made. Rising construction costs, surplus labour and easy availability of granular backfill makes stone columns a very attractive alternative to conventional methods in Bangkok. An effort has been made in studying the stone columns to improve the load carrying capacity of soft and compressible soils underlying Bangkok. A review of the existing state of art of stone column analysis has been done. The exact nature of the interrelated performance of stone columns and institu soil is extremely complicated and most analysis to date are empirical and semi-empirical in nature. The development of theoretical models simulating the stone column deformational behavior has been undertaken by numerous authors. The equations and design procedures suggested by these agree well with field tests conducted on individual stone columns. Several factors like (i) compressibility of the insitu soil (ii) plastic and elastic behavior of the stone(iii) stress distribution between the stone column and the insitu soil (iv) time settlement relationships of the composite mass, should be considered in the load-deformational behavior of the stone column. A thorough subsurface investigation and evaluation of geotechnical properties are essential for the design of stone columns and the selection of the most suitable alternative. Field performance information for the stone column improved ground is needed for the future design and also to develop a better understanding of the mechanistic behavior of the stone columns. |
