  • Kulathilaka, SAS; Sagarika, DKNS [Conference-Extended-Abstract]
    Finding cost effective, and relatively quick solution to handle the thick layers of soft peaty clays is a major challenge faced by Sri Lankan Geotechnical Engineers. Number of . different methods had been tried out to ...
  • Dias, WPS; Jayanandana, ADC [Article-Abstract]
    This paper describes the condition assessment of a 30 year old cement works, where some of the structures were clearly deteriorated. It was carried out for the purpose of obtaining material properties needed for evaluating ...
  • Kugan, R; Puswewala, UGA; Kulathilaka, SAS; Peiris, TA [Conference-Extended-Abstract]
    The first rational theory to explain the settlements occurring in saturated clays was the 1- D theory of consolidation proposed by Terzaghi (1925). One of the main advantages of the theoretical modelling of consolidation ...
  • Madanayake, OC; Jayawardane, AKW; Wickramarachchi, N [Conference-Extended-Abstract]
    Since the age of the industrial revolution, many technologies have surfaced, yet none could compare to the reception that computers received. It is by far the most popular technology to knock on the doors of the modern ...
  • Rathnasiri, RM; Peiris, TA; Puswewala, UGA [Conference-Extended-Abstract]
    In model soil slope studies as related to Geotechnical Engineering. the engineers arc interested in the failure surface and the maximum shear strength developed there upon failure. Monitoring the displacements and strains ...
  • Jayasinghe, MTR; Jayasena, WMVPK
    Axial shortening of columns in reinforced concrete buildings is a phenomenon that was commenced from the day of commencement of concrete building construction. However, this seems to start creating problems only before ...
  • Jayasinghe, MTR; Sugathadasa, PTRS [SRC-Report]
    In BS 8110 : Parti : 1985, the improved durability of concrete was achieved by using mixes with higher strength such as grades 25 and 30. However, volume batched nominal mix of 1:2:4 (20 mm ) is still used in many ...
  • Jayasinghe, MTR [SRC-Report]
    Sri Lanka has diverse climate conditions that can be broadly divided into tropical wet zone, dry zone and tropical uplands. The designing of passive houses for tropical dry zones would be a challenging task since quite ...
  • Dias, WPS; Subrahmanian, E; Monarch, IA [Article-Abstract]
