A new approach is proposed to evaluate the non-limit active earth pressure in c–? soil based on horizontal slices method and limit equilibrium method, which takes into account arching effect, displacement, mobilized friction angle, tension cracks, shear stress of layer. The accuracy was demonstrated by comparing experimental results other theoretical methods. comparison showed that appropriate ...

Studying mining fracture development is vital for geotechnical and engineering geological disaster prevention. This research assesses crack effects on rock mass stress equilibrium during coal mining, potentially causing disasters such as land subsidence landslides. Using fractal geometry theory, the present study investigates of horizontal vertical cracks, revealing their propagation patterns. ...

The road performance decay law of EACRM under freeze-thaw cycles was studied using laboratory tests on the macroscopic scale in order to comprehensively analyze serious damage mechanism emulsified asphalt cold recycled mixture (EACRM) regions during service period. surface cracking behavior, internal void evolution characteristics, and mortar morphology were by means digital speckle, industrial...

Purpose This paper aims to Test the capabilities/accuracies of four deep learning pre trained convolutional neural network (CNN) models detect and classify types highway cracks, as well developing a new CNN model maximize accuracy at different rates. Design/methodology/approach A sample 4,663 images cracks were collected classified into three categories namely, “vertical cracks,” “horizontal ve...

This study undertaken on a nine-year-old cracked concrete panel further investigates the impact of cracks corrosion performance conventional steel reinforcement in marine-exposed to explain observed monitoring data. The present data covers seven 1.80 m long (12.6 m) reinforcing bars embedded good quality (w/b = 0.40 and cover >75 mm). Each bar was crossed by two horizontal (surface crack widths...

Two decades of operating experience have shown that reducing the corner radius from 12–16 mm to 3 or 4 mm A finite element thermal stress model to compute is beneficial in reducing longitudinal corner cracking.4 In the thermomechanical state of the solidifying shell addition to lessening crack frequency, decreasing the corner during continuous casting of steel in a square billet radius also ten...

PURPOSE The aims of the present study were to compare the image quality and visibility of tooth cracks between conventional methods and swept-source optical coherence tomography (SS-OCT) and to develop an automatic detection technique for tooth cracks by SS-OCT imaging. METHODS We evaluated SS-OCT with a near-infrared wavelength centered at 1,310 nm over a spectral bandwidth of 100 nm at a ra...
