Unconfined compressive strength (UCS) is an important parameter of rock and soil mechanical behavior in foundation engineering design construction. In this study, salinized frozen selected as the research object, GDS tests, ultrasonic scanning electron microscopy (SEM) tests are conducted. Based on classification method model parameters, 2 macroscopic 38 mesoscopic 19 microscopic parameters selected. A machine learning used to predict considering three-level characteristic parameters. Four...
High-modulus asphalt mixture (HMAM) is one of the most effective materials to enhance rutting resistance pavement and upgrade sustainability. The objectives this study are investigate modulus properties different HMAMs their correlation with resistance, propose reasonable evaluation indicators, analyze mechanisms (hard asphalt, polyethylene, dissolved polyolefin). effect three two styrene-butadiene-styrene (SBS) modifiers on mixtures’ were evaluated by dynamic test wheel track test, results...
Buildings are always affected by frost heave and thaw settlement in cold regions, even where saline soil is present. This paper describes the triaxial testing results of frozen silty clay with high salt content examines influence confining pressure temperature on its mechanical characteristics. Conventional compression tests were conducted under different pressures (0.5–7.0 MPa) temperatures (−6 °C, −8 −10 −12 °C). The test show that when less than 1 MPa, dominated brittle behavior X-shaped...
Abstract The objective of this paper is to examine the reliability three-dimensional (3D) laser detection technology data density for crack width results cement slabs. Four groups concrete elevation with a 0.5–1.5 mm were obtained using an indoor 3D system, and models established. nonlinear least squares method was applied fit fracture section, determined by peak value analysis. demonstrate that lateral spacing points exerts large impact on mean discrete degrees results. point positively...
Water inrush disasters in karst areas have caused great losses to underground engineering construction, so it is urgent control water gushing pipelines. In this paper, solution polymerization used prepare a grouting and sealing expanded matrix material disasters. Noncovalent weak interactions were improve the surface properties of material, effects natural polymer content on studied, modified with an optimal response rate was prepared. A cross-linked curing agent (CCA) developed synthesized,...
Cement slurry and cement‐sodium silicate are most widely applied for soil grouting reinforcement project. The viscosity change of cement is negligible during period presumed to be time independent, while the increases with quickly dependent. Due significant rheological differences between them, quality increasing characteristics parameters may different. Those main factors design. In this paper, a large‐scale 3D simulation device was developed simulate surrounding curtain tunnel. Two series...
In order to study the interlayer shear behavior of bridge deck pavement, a numerical simulation was conducted analyze influence varying interfacial conditions on stress at bottom pavement layers under moving loading effect. Moreover, strength different adhesive and waterproof materials evaluated by conducting laboratory tests. The results showed that improving bonding condition upper led reduction layers. With increase friction coefficient interface full state, resulting layer declined...
In the context of global pandemic COVID-19, use and disposal medical masks have created a series ethical environmental issues. The purpose this paper is to study evaluate high temperature properties thermal storage stability discarded-mask (DM)-modified asphalt from multi-scale perspective using molecular dynamics (MD) simulation experimental methods. A tests was conducted physical, rheological, microscopic samples. These include softening point, rotational viscosity, dynamic shear rheology...
