Article
Full-text available
The assessment of soil erosion risk has been widely studied, and various methods have been established. However, most of the methods require extensive field and laboratory works that are time-consuming. The previous literature mainly focused on utilizing the existed empirical models like USLE and its derivatives. The establishment of empirical corr...

This study determines the effectiveness of horizontal drains on a slope which refers to a landslide at Putrajaya, Malaysia, in 2007. The incident buried 27 cars, and about 1200 people were transferred to a safe place. The main cause was identified as continuous and heavy rainfall. In Malaysia, abundant rainfall is common during the wet season. Ther...

Spectral analysis of surface wave (SASW) method for in-situ non-destructive testing of stiffness profiles of soil and pavement sites have undergone various improvements since its inception during the 1980s. Improvements have been in both data-acquisition (sampling and sensors) as well as in data-processing (forward calculation and inversion algorit...

One of the complex processes in spectral analysis of surface waves (SASW) data analysis is the inversion procedure. An initial soil profile needs to be assumed at the beginning of the inversion analysis, which involves calculating the theoretical dispersion curve. If the assumption of the starting soil profile model is not reasonably close, the ite...

The climate of Malaysia, which is hot and humid, has a great impact on soil-root interaction. This study aims to determine the influence of soil-root interaction in slopes, which is calculated in the form of factor of safety. A numerical slope model is studied with Vetiver grass (Vetiveria Zizanioides sp.) as the vegetative cover at a residential p...

Nowadays, a large amount of municipal solid waste (MSW) is generated due to the rapid urbanisation in developing countries leads to the demand for larger and higher capacity landfills. Bioreactor landfill technology has been introduced to accelerate the stability of landfill and to solve the issue of limited landfill area. However, the accelerated...
Article
The structural integrity of pavement is the key to keeping motorists safe and comfortable while driving on roads. Failure to maintain structural integrity of pavement results in traffic disruptions and even causes havoc on cars and pedestrians alike. In this paper, an imaging technique for structural integrity of a concrete pavement was proposed to...
Article
Single-stage construction technique and multi-staged construction technique are two embankment-construction techniques that are generally used on soft soils. A single-stage construction technique is usually used for fast construction of comparatively low-height embankments. A multi-staged construction technique is mostly used for construction of hi...

This article presents a comparative study of the behaviour of clayey soil reinforcements using stone column ground improvement by means of numerical analyses. Two-dimensional finite element analyses with commercially available software, PLAXIS, were performed on end-bearing stone columns using 15-noded triangular elements to investigate the impact...
Article
This paper presents the feasibility of using Scholte waves by spectral-analysis-of-surface-waves (SASW) method for near-surface soil stiffness profiling. Scholte-wave measurement does not require ground coupling thus fast SASW can be performed. Scholte wave propagation at the air-to-soil interface was analyzed first by Finite Element (FE) simulatio...
Article
This paper presents the effect of input source energy on the results of spectral analysis of surface wave (SASW) evaluation of flexible pavements in terms of maximum and minimum wavelength. A series of surface wave tests, namely the SASW test, were done on asphalt pavement using four steel balls with different masses as sources. These sources were...
Article

This paper discusses the effectiveness of the industrial training from the perspective of students who have undergone 12 weeks of industrial training. A questionnaire was distributed to 47 Third Year students at the Civil and Structural Engineering Department (JKAS), Faculty of Engineering and Built Environment, Universiti Kebangsaan Malaysia (UKM)...
Conference Paper
Full-text available
This paper introduces the use of a seismic technique, the Enhanced Resonance Search (ERS), to assess airport runway profile and evaluate its strength variation with depth. ERS technique combines the advantages from the Spectral Analysis of Surface Wave (SASW) method, which measures the vertical variation of shear wave velocity and the resonance met...
Article
Full-text available
A series of surface wave tests, namely the Spectral Analysis of Surface Wave (SASW) test, was done on asphalt pavement to study the effect of receiver distance, S; the height of dropping steel balls, H; and the mass of the source, m on the results of SASW evaluation. For each test, four steel balls with different masses, namely0.067kg, 0.228kg, 0.5...
Article
Deflections of structural elements like railway tracks and bridge spans, at which a reference point is not available for deflection measurement, have posed a dire predicament in the industry. It is because a reference point for measurement of deflections may not be available at most of structures due to the vibration of a whole structure. Even a mo...

Social demand for the stability of structures lead to the development of the technology to accomplish it. The non-destructive seismic technique, which is able to assess structural integrity of infrastructures, belongs to this category. Seismic technique is focused on the measurement of seismic velocity propagating through the material, and has to u...

Recently a limited section of trackbed with ballast at KTX railway were reported to have settled down and led to problems such as reduced speed and passenger discomfort. Therefore, an urgent remedy for the settled trackbed is required to recover normal operation of KTX trains. In this paper, a new technique is proposed to visualize the elastic modu...

Electrical noises like self potential, burst noises and 60-Hz electrical noises are one of the causes to reduce reliability of electrical resistivity survey. Even the PDC-R (Pseudo DC resisitivity) technique, recently developed, is suffering from the problem of low reliability due to electrical noises. That is, both DC-based and AC-based resistivit...
