• Comparison between empirical, numerical and practical compression capacity of rock socketed bored and cast in-situ pile : a case study 

  Silva HAM [Thesis-Abstract]

  The development of tall structures as a rapidly developing trend in Colombo-Sri Lanka is evident during the recent past due to the high land prices. These tall structures require to be founded on strong substrata and piling ...
• Soil as a foundation material 

  Wijesinghe, S [Thesis-Full-text]

  Cement Stabilized Soil Blocks are now considerably popular in the construction industry as an alternative building material to burnt bricks and cement sand blocks. It provides a timely solution for the over exploitation ...
• Utilization of building debris as aggregates in stone column construction in Sri Lanka 

  Sanjeewa, KWD [Thesis-Full-text]

  Due to rapid development and population growth, construction industry has emerged with few recent problems. The major problem faced by the construction industry is the scarcity of construction material and disposal of ...
• Study on utilization of building debris in road construction in northern province of Sri Lanka 

  Shankar, P [Thesis-Full-text]

  Due to rapid development and population growth, construction industry has emerged with few new problems. The major problem faced by the industry is the scarcity of construction material and disposal of construction waste ...
• Possible use of bottom ash in embankment construction 

  Chrishanthi, JAC [Thesis-Full-text]

  Bottom ash is a solid residue byproduct produced by coal burning for electricity generation. In Sri lanka it has not been developed proper system to dispose of this bottom ash other than using small amount for concrete ...
• Enhancement of the stability at the site of an ancient landslide in a road cutting with drainage and reinforcement - case history at Ginigathhena 

  Lakruwan SOADM [Thesis-Abstract]

  Engineers involved in infrastructure development projects in the hilly terrain of Sri Lanka encounter ancient landslides which could be triggered by rainfall or construction activities. One such landslide was encountered ...
• Application of dynamic and vibro compaction methods for densification of granular fill in reclaimed land in Sri Lanka 

  Samarasinghe AI [Thesis-Abstract]

  In the recent past, Government of Sri Lanka executed a large-scale reclamation project in Sri Lanka to add a brand-new land of 267-hectare to the Capital, Colombo with strategy of converting Colombo as a commercial hub ...
• Investigation on the equivalent modulus of subgrade reaction of layered soil 

  Mathuwanthy T [Thesis-Abstract]

  ‘Modulus of subgrade reaction’ is the ratio between the pressure applied on the soil and the corresponding settlement. There is no theoretical relationship found to obtain equivalent subgrade modulus of layered soil. Top ...
