In civil engineering, the study of embankment settlement on soft ground is a vital geotechnical task in order to maintain serviceability of the road embankment, pavement, and facilities. This paper presents a study on settlements of road embankment on soft ground using vertical drains, including prefabricated-vertical drain (PVD), sand drain (SD), and sand compaction pile (SCP) on a number of packages of Hanoi – Haiphong Expressway Construction Project.

This work aims to study the crack pattern in masonry-like structures by a simplified description of the medium using a variational damage model. In literature, when modeling fractures in masonry structures, capturing both fracture types, cracks in units, and cracks at the interface simultaneously, usually requires a complicated scheme.

In this paper, we identify and evaluate 42 tower crane safety risk factors specific to the Vietnamese construction industry based on their probability of occurrence, severity of impact, and associated risk levels. The paper reveals that the most probable risk factor is “Unfavorable winds (including intensity, direction, etc.)” with a mean value of 3.641.

The research "Solving constrained optimization tasks in civil engineering using εDifferential Evolution developed with Visual C#. NET" work aims at constructing an evolutionary algorithm based approach for solving complex constrained optimization tasks. The  -Differential Evolution (  -DE) proposed by Takahama, et al. [1], is selected as the employed evolutionary approach. The  -DE has been proven to be capable optimizer for tackling sophisticated problems in various engineering field. In this study, this optimization method is developed in Visual C#.

Lightweight structures with soft inclusion material, such as hollow core slabs, foam sandwich wall, pervious pavement are widely used in construction engineering for sustainable goals. Voids and soft inclusion can be modeled as a very soft material, while the main material is modeled with its original rigidity, which is so much higher than inclusion’s one.

Unexpected defects of concrete in a completed bored pile can arise during the construction stage. Therefore, post-construction testing of bored pile concrete is an important part of the design and construction process. The Cross-hole Sonic Logging (CSL) method has been the most widely used to examine the concrete quality.

This paper presents the long-term morphological changes of the sand spits at the Ken Inlet in Ha Tinh Province and Phan Inlet in Binh Thuan Province, Vietnam. The analysis results show that the sand spit morphology at Ken Inlet was drastically changed before the completion of the Da Bac sluice gate construction in 1992, after that the sand spit elongation rate became stable at a rate of about 68 meters per year.
