| Abstract: | The lateritic soils are usual a problem soils in subtropic area, ie a residual clays to be formed from laterization. Lateritic soils, especial carbonate rocks red loams distribute widely in South China.They frequently have a harmful influence on engineering construction in arid and half-arid region. Until now, the special study on the distribution and properties of quaternary lateritic soils is lacked in North China.The problem soils with .high void ratio,high water content,high plasticity and med-low compressibility are found in Dalian New Harbour construction.The systematical researches for the mineralogy, petrology,physico-cbemistry and engineering properties of this soils and their mother rock have been made by authors. This paper deals with the formation mechanism of the lateritic soils and their engineering properties in Dalian New Herbour.The result indicates that the researched lateritic soils is a laterizaticn product of the montmorillonization trachybasalt in medium temperate climate zone. |
