ABSTRACT
This chapter presents the structure–foundation–soil interactions and ground improvement systems. There are numerous environmental geotechnical problems; however, these problems require knowledge from other disciplines. The chapter focuses on wetland, marine margin land, dredging and reclaimed land, ground surface subsidence, waste control facilities, landfill technology, arid land, and desert regions with an emphasis on causes, failure mechanisms, and prevention and control from an environmental geotechnology point of view. It discusses numerous man-made causes of ground subsidence such as dewatering, mining, removing natural gas or petroleum and construction operations such as deep excavations. The chapter also presents the domestic and landfill technology and aims to devote hazardous and radioactive waste. There are five types of disposal or management methods for radioactive elements. They are storage, vitrification and solidification, isolation, emplacement, and elution. The chapter examines controlling of radioactive toxic radon gas (Ra). There are two major methods to mitigate the Ra, namely the passive approach and the active approach to the problem.
