Evaluation of Soil liquefaction in Sri Lanka – A dynamic Approach Using Geotechnical Investigation Data

Kumarasiri, C; De Silva, N; Abayakoon, S [Conference-Full-text]

Soil Liquefaction is a process, where granular soils below the ground water table temporarily lose its strength and behaved as a viscous fluid rather than a solid. The porewater pressure is suddenly increased during an ...
Failure Analysis of a DBST Road Using Mechanistic-Empirical Method

Mampearachchi, WK; Marasinghe, DL; Dahigamuwa, RMTM; Wanniarachchi, WDNG [Conference-Full-text]

The objective of this research is to analyze a failure of a DBST road section using a Mechanistic – Empirical method. For this analysis, failure of A15- Trincomalee-Batticaloe road was selected.This particular road section ...
Identification of WebGIS Development Potential and Issues – A land and Water case Study Application for Moratuwa, Sri lanka

Chandramali, EAG; Wijesekera, NTS [Conference-Full-text]

Popularity of internet use is rapidly increasing. Hence, the demand is high for Web based GIS tools. The need to handle heavy maps and attribute datasets, often increase issues especially with respect to the time taken ...
Investigation of Hydraulic Performance of Gabion Structures

Hettiarachchi, SSL; Samarasekara, RSM; Priyankara, SS; Silva, HAM [Conference-Full-text]

This paper presents selected results of a detail study of the transmission and reflection performance of gabion structures used in harbour and costal engineering applications. The performance of the structures is discussed ...
Investigation on Uplift Capacity of Shallow Foundations on Cohesionless Soil

Koorala, SKDCP; Kumara, MKSN; Edirisinghe, EAL; De Silva, LIN [Conference-Full-text]

Shallow foundations are commonly used in Sri Lanka for communication towers, power transmission towers and towers for wind turbines. The design of these foundations is based on several assumptions and therefore, a large ...
Is Course Correction Needed for Direction of Research in Concrete

Holey, S; Silva, A; Perera, HTP; Wijayakulatilaka, WGMA [Conference-Full-text]

This paper is an endeavour to highlight importance of realizing potential of research in “value addition” or “making” process of concrete. Authors, based upon their experience as link of cement manufacturing and construction ...
Methodology to Develop a Driving Cycle for a Given Mode and Traffic Corridor; Case Study for Galle Road, Colombo, Sri Lanka

Gamalath, I; Fernando, C; Galgamuwa, U; Perera, L; Bandara, S [Conference-Full-text]

A driving cycle is a speed time profile which represents the driving characteristics of a selected area. This can be of use to both legislative and non legislative purposes such as development of emission inventory, ...
Recognizing Temporal Variability of Lumped Watershed Behaviour and Evaluating Averaged Performance of a Hydrological Model

Wijesinghe, WMD; Wijesekera, NTS [Conference-Full-text]

Majority of watersheds associated with civil engineering infrastructure projects are ungauged and most commonly used method to determine streamflow in ungauged basins is mathematical modelling with the use of Synthetic ...
Selecting a Usability Evaluation User Group – A Case Study the Development of a Hydro-GIS Tool Aiming Urban Flood Mitigation

Pradeep, RMM; Wijesekera, NTS [Conference-Full-text]

Flash floods which are becoming a common occurrence due to poor planning in the urban areas need user friendly tools for land managers to arrive at suitable alternatives. These tools require incorporating spatially ...
Study on Ground Vibration Due to Rock Blasting of Metal Quarry: A Case Study

Madanayaka, TA; De Silva,LIN; Dharmarathne, PGR [Conference-Full-text]

This study was carried out to compare vertical and horizontal bench blast(s) at a granitic gneiss rock quarry located in Colombo, Sri Lanka and predict the resulting peak particle velocities of ground vibration levels. ...
Study on Palmyrah as a Reinforcement Material

Baskaran, K; Mallikarachchi, HE; Jayasekara, MJPLM; Madushanka, GAT [Conference-Full-text]

Most developing countries are confronted with acute housing shortage due to their over dependence on expensive, imported building materials. So there is an intense search for innovation of locally available, nature ...
Study on Rebound Values on Inclined Planes

Baskaran, K; Liyanage, KLDO; Munasinghe, NT; Gunawardana, WWCJ [Conference-Full-text]

Non-Destructive Testing (NDT) methods are widely used in the industry to assess the parameters like strength and durability of an existing structure. They offer significant advantages of speed, cost and lack of damage ...
