Abstract Rock mass quality evaluation is a challenging task in geotechnical investigations given the natural heterogeneity and limited data. These mainly depend on traditional drilling tests. However, such tests are expensive time consuming, provide point measurements, cannot be conducted steep topographic areas, thus cause uncertainties geological model. Conversely, geophysical methods as electrical resistivity tomography (ERT) non-invasive, user-friendly, fast. In this work, we establish...
The phenomenon of landslide spatial aggregation is widespread in nature, which can affect the result susceptibility prediction (LSP). In order to eliminate uncertainty caused by an LSP study, researchers have put forward some techniques quantify degree aggregation, including class index (LAI), widely used. However, due limitations existing LAI method, it still uncertain when applied study area with complex engineering geological conditions. Considering a new dual-frequency ratio (DFR), was...
Determination of rock mechanical parameters is the most important step in mass quality evaluation and has significant impacts on geotechnical engineering practice. Rock integrity coefficient (KV) one efficient parameters, which conventionally determined from boreholes. Such approaches, however, are time-consuming expensive, offer low data coverage point measurements, require heavy equipment, hardly conducted steep topographic sites. Hence, borehole approaches cannot assess subsurface...
Seawater intrusion is a major challenge in many coastal areas all around the world, mainly caused by over-exploitation of freshwater resources, climate change, and sea-level rise. Consequently, seawater reaches several kilometers inland, thus making resources polluted unsuitable for human use. Conventionally, fresh-saline water interface delineated number laboratory tests obtained from boreholes. However, such suffer efficiency terms data coverage, time, cost. Hence, this work introduces...
Investigation of a hard rock site for the development engineered structures mainly depends on delineation weathered and unweathered rock, fractures/faults. Traditionally, borehole tests are used in such investigations. However, approaches expensive time-consuming, require more equipment, cannot be conducted steep topographic areas, provide low coverage area with point measurements only. Conversely, geophysical methods non-invasive, economical, large an through both vertical lateral imaging...
Abstract Evaluation of rock mass quality is necessary for the proper design engineering infrastructures. Rock designation (RQD) an important geotechnical parameter in classification. However, given limited data and natural heterogeneity, evaluation a challenging task. Traditionally, mechanical parameters are obtained from drilling tests. tests only provide single‐point information thus cannot detailed underground information. Moreover, boreholes costly time‐consuming, still be carried out...

Graphdiyne quantum dots (GDQDs) have attracted increasing attentions due to its unique electronic, optical, and electrochemical properties. However, the low conductivity yield of GDQDs limit their application. Here, nitrogen-doped graphdiyne (N-GDQDs) are firstly synthesized by a simple, friendly one-step hydrothermal method. The N-GDQDs show maximum emission at 420 nm under excitation wavelength 319 nm. doping N modifies surface defect further greatly improves (from 14.6% 48.6%). In...
