Polyurethane (PU) is increasingly adopted as grouting materials in the non-excavation
rehabilitation of infrastructures. The compressive strength of PU materials is the key to achieving …

The diffusion of cement slurry in a fracture with flowing water is an important factor ensuring
the grouting effect and a key factor influencing the environment, including natural and social …

Conventional algorithms are not sensitive to small objects like pavement cracks. We developed
a pavement crack detection method based on a convolutional neural network (CNN) with …

Grouting methods are known to effectively remediate the groundwater inrush in tunnels with
weak water-rich sand layers. However, the diffusion characteristic of cement slurry flowing in …

In this study, nano-Fe 3 O 4 supporting on granular activated carbon (NFGAC) were prepared,
characterized and used as an individual additive to promote the anaerobic digestion of …

The bonding performance between the anchor anchorage body and soil is an important
index to evaluate the anchoring performance of anchor bolts. In this work, the vertical …

Contact problems are among the most difficult issues in mathematics and are of crucial
practical importance in engineering applications. This paper presents a scaled boundary finite-…

The selection of optimal intensity measures (IMs) has been recommended for generating
the seismic demand models with different probabilities by researchers since the seismic IMs …

The fine aggregate of siliceous rock has the advantages of high production efficiency, stable
yield and low construction and transportation cost. The Yangxi concrete dam was firstly …

Wire breakage is a regular occurrence of prestressed concrete cylinder pipe (PCCP). This
research investigates the impact of fiber reinforced polymer (CFRP) width and thickness on …
