โœฆ Synopsis

An attempt has been made to investigate the lime induced permeability changes in the permeability and engineering behavior of different lime column treated soil systems. Lime columns treated marine clay shows an increase in permeability up to a maximum value of 15-18 times that of untreated soil with time. The shear strength of the treated soil systems show an increment up to 8-10 that of untreated soil within a period of 30-45 days curing. In the case of lime injection systems, the permeability has been increased up to 10-15 times that of untreated soil, whereas the strength of the soil has been higher by 8-10 times that of untreated soil. Further, consolidation tests show a reduction in the compressibility up to 1/2-1/3 of original values. The test results revealed that both lime column and injection techniques could be used to improve the behaviour of underwater marine clay deposits.

The necessity to tap natural marine resources from the ocean beds represents a considerable challenge for the construction of offshore structures on weak marine deposits. The use of lime to improve the behaviour of soft clays is not new. The present investigation examines limeinduced changes in the

The use of lime to improve the engineering properties of weak marine clays is a common method from the past. Recent studies indicate that the various foundation problems occurred with passage of time for offshore structures due to hostile wave conditions and adverse climatic conditions. Hence, there

The treatment of fine-grained soils with lime makes the soil system less sensitive to the changes in stress and other environmental factors. In the present investigation an attempt has been made to examine the nature of reaction products formed in a marine clay due to lime treatment using scanning e
