Compressibility characteristics of unsaturated soil

Krichikeshan, I; Kulathilaka, SAS [Conference-Abstract]

Conventional Terzaghi's consolidation theory is developed for saturated soil. However, in practice the concept is used with unsaturated soils as well. The behaviour of unsaturated soils is quite different due to the ...
Establishment of soil water characteristic curves for Sri Lankan residual soils

Ranasingha, RHATD; Kulathilaka, SAS [Conference-Abstract]

The water content in an unsaturated soil is a function of the suction present in the soil. This relation between soil water content and suction could be represented by the soil-water characteristic curve, which is a plot ...
Improvement of compressibility characteristics of waste material by dynamic compaction

Rathnayaka, RIA; Kulathilaka, SAS [Conference-Abstract]

Open dumping is the most prevalent method of waste disposal in Sri Lanka. These sites, which are currently used as waste dump yards in urban areas, will have to be rehabilitated to be converted to be used as parks, roads ...
Laboratory modelling of infiltration into unsaturated residual soils

Somarathne, PAU; Kulathilaka, SAS [Conference-Abstract]

Rain induced failures in slopes made of residual soils are a major concern in Sri Lanka. Sri Lankan sloping grounds are made of colluvial soils, residual soils, and rocks at different levels of weathering. Soils at upper ...
Use of the concept of capillary barriers to optimize the support of deep vertical excavations in unsaturated soils

Prasanna, R; Kulathilaka, SAS [Conference-Abstract]

Deep excavation in the construction industry became vital because of the lack of availability of land in the populated urban areas to provide facilities such as parking. In a deep excavation it is necessary to ensure ...
