SOFT CLAY BEHAVIOUR ANALYSIS AND ASSESSMENT
As a civil engineering material, soil is as important as steel or concrete. The uniquefeature of this material is that it largely comes engineered by nature, unlike othermaterials which have to be manufactured or processed to specific requirementswith the product quality ensured. So geotechnical engineers concentrate on thecardinal task of characterizing the properties of this natural large volume material,before integrating the results with analysis to design contemplated structures tomeet the strict performance requirements.
This book is primarily concerned with the analysis and assessment of the be-haviour of soft clay in compression and shearing, both in their undisturbed andstrengthened states. Soft clay deposits are widespread and cover many coastal re-gions of the world, such as in Japan, Eastern Canada, Norway, Sweden and otherScandinavian countries, India, and the South East Asian countries. Another fea-ture of these coastal regions is that certain shore areas are lowlands, quite oftendue to subsidence on account of excessive withdrawal of ground water. The Cen-tral Plain (Chao Phraya) of Thailand and Saga Bay in Southern Japan are someexamples of lowland areas. All these are inhabited zones, having undergone ex-tensive urbanization and industrialization. Further extensive developmental ac-tivities are apace in many lowland areas to promote human activities, such as ag-riculture, industry, housing and such other infrastructure facilities.
