Prediction of Compaction Parameters of Soil using Support Vector Regression

 

Abstract

Compaction parameters determination in the laboratory require considerable time and effort that can be saved by using empirical correlations at the early stages. This paper introduces some efforts to predict the compaction properties of soils using the index test results. Apart from the experimental result, the result from other literature have also been considered in the analysis here. Different statistical investigation such as histogram, ACF, PACF, kernel function, correlogram and cross correlogram are used to find the relationship of liquid limit, plastic limit and plasticity index with optimum moisture content and maximum dry density. Regression analyses are done with support vector machine algorithm. The best R squared value found from the predicted equation is 0.86 for optimum moisture content and 0.91 for maximum dry density.

Keywords: Prediction; Optimum moisture content; Maximum dry density; Compaction parameters; Support vector regression

Iris Publishers- Open Access Journal of Civil Engineering

Image
Iris Publishers - Open Access Journal of Civil Engineering Structure, Building Envelop and Form integration in Architecture Contemporary Architecture is witnessing a significant transformation, because of developments in technology that is releasing architects from the use of static forms and historical construction methods, to the use of more dynamic forms that integrate elements of structure, building envelop and form in designs. This paper briefly examines developments in architecture over time, in order to situate and discuss the current emerging trend of integration. The article starts from exploring the history of architecture and the form of buildings in the different eras. It then moves on to discuss the contemporary trend in building form, structure and envelope integration, exploring some of the factors that are drive the trend and discussion of implication for the form of future architecture.

Quality Control of Concrete in the Southern Region of Kingdom of Saudi Arabia Using Local Materials | Osama K Adwan

Osama K Adwan |  Quality Control of Concrete in the Southern Region of Kingdom of Saudi Arabia Using Local Materials Research Article A common concern amongst civil engineers is producing a good quality concrete on-site. This paper reports results of a study carried out to examine the quality of normal strength concrete production in the southern region of Kingdom of Saudi Arabia (KSA) made from local coarse aggregate namely Basalt. As all data were analyzed and examined statistically using Chebyshev’s theorem and the Statistical Empirical Rule (SER) method presented herein. It is concluded that, the normal distribution of all test results -in terms of the quality of concrete mix- was strongly agree with Chebyshev’s theorem and ACI 318-14 section 5.6.3. In addition, these results were considerably better than the Statistical Empirical Rule (SER) method. Overall, these concrete mixes, in this investigation, with 28 days compressive strength of 35 MPa can be used confidently in concr...
