The 781m twin tunnel in line No 1 Ben Thanh – Suoi Tien was the first tunnels constructed by Earth Pressure Balance Tunnel Boring Machine (EPB TBM) in the urban area in Ho Chi Minh City, Vietnam. Field data on a surface settlement at three sections, measured during the construction period from May 2017 to June 2018, are used for back analyses on the development of surface settlement with the corresponding advancement of the EPB TBM.

As one of the longest and largest rivers on Earth, the Mekong river flows along six countries. Mekong River Basin is a home of various plants, animals and fish as well as providing great economic value to supply for more than sixty million people living along it. Nevertheless, the natural environment and local communities are on the verge of alarming danger because of huge hydropower dam constructions.

The morphotectonic features of the TGFZ and the distribution of the epicenters of earthquakes over magnitude 5.0 show that this fault zone remains active today. In this study, the deformation of the TGFZ is determined with high sensitivity using geodetic measurements. To obtain accurate information about the deformation of the TGFZ, 24 GNSS sites and two continuously operating reference stations were constructed in the southern part of the TGFZ. Between 2018 and 2020, Global Navigation Satellite Systems (GNSS) measurements were made on this network.

High levels of environmental radioactivity are caused by the composition of minerals in the earth’s crust and the impact of prospection and utilization of natural sources, mainly due to the presence of 40K and radionuclides of 238U and 232Th series. Radium equivalent activity (RaEq) was calculated to assess the risk associated with primordial radionuclides.

Utilization of Coal bottom ash (CBA) as well as finding the solutions to prevent saline intrusion, meeting the needs of coastal infrastructure development have been considered by the authors of the article for a long time. In this study, the authors focused on analyzing capillary characteristics in order to find a suitable group of CBA particles, which can be applied in the design of foundations with the high ability in restricting or preventing the effects of salt in saline groundwater.

The paper investigates the physical characteristics and mechanical behaviors of Bazan soil. Based on that, proposes the approach for quality improvement and design criterion when using Bazan soil for homogeneous earth dams. The result of experiments reveals that Bazan soil has low dry density and high optimum moisture content, which is the cause of difficulty in the construction phase. Whereas, if suppling 10- 12% of mixture weight by using grit, the mechanical properties of mixture is going to be improved significantly and can be used for filling the embankment dam.

This study estimated the time series of surface water area by processing Landsat images from the Google Earth Engine platform. Then, the area – volume – elevation relationship constructed from DEM was used to derived the water level and volume from the surface water area datasets. The results showed that remote sensing enables to monitor temporal variations of water level and volume of reservoirs.

Many offshore structures are subjected to overturning moments due to wind load, wave pressure, and ship impacts. Also most of retaining walls are subjected to horizontal forces and bending moments, these forces are due to earth pressure. For foundations in such structures, usually a combination of vertical and batter piles is used. Little information is available in the literature about estimating the capacity of piles under uplift. In cases where these supporting piles are not vertical, the behavior under axial pullout is not well established.
