RISExperimental Study on the Stability of Railroad Silt Subgrade with Increasing Train Speed
Publisher: American Society of Civil Engineers
Abstract: The comfort and safety of a moving train is largely determined by the dynamic response of the railway track and its foundation (i.e., subgrade). To study the dynamic stability of a silt subgrade subjected to train traffic ...
Ultrasonic Measurement of Scleral Cross-Sectional Strains During Elevations of Intraocular Pressure: Method Validation and Initial Results in Posterior Porcine Sclera
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Background. Scleral biomechanical properties may be important in the pathogenesis and progression of glaucoma. The goal of this study is to develop and validate an ultrasound method for measuring ...
Research on Effect Factors of Mechanical Response of Polyethylene Gas Pipeline in Karst Area Based on Element Birth and Death Technique
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Buried gas pipelines in karst area are inevitably affected by the geotechnical activities, which is difficult to resist the permanent ground displacement caused by soil dislocation and surface damage. In this paper, abaqus ...
Building Rectification by Underexcavation and Practical Design Method
Publisher: ASCE
Abstract: An 11-story high-rise building with a shear-wall structure utilized a raft foundation based on a deep alluvial deposit. After structure completion, the building tilted beyond acceptable limits. This paper presents the ...

Risk Analysis of Gas Pipeline in Karst Area Based on Multilevel Hierarchical Structure Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a risk analysis method of gas pipeline in karst area based on the integrated model of the decision-making trial and evaluation laboratory–interpretive structural model (DEMATEL– ISM) method and the cross-impact ...
A Leakage Rate Prediction Model for Flange Connections Based on the Relative Deformation of Gaskets
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flange connections are widely used in industries such as petrochemicals and nuclear power, where they encounter complex mechanical and thermal loads, making them potential sources of leakage. Leakage not only affects the ...
Effects of Principal Stress Rotation on the Cumulative Deformation of Normally Consolidated Soft Clay under Subway Traffic Loading
Publisher: American Society of Civil Engineers
Abstract: The authors investigated the effects of principal stress rotation (PSR) on the traffic load–induced settlement of subways in soft subsoil. Here, a series of hollow cylinder tests on normally consolidated, medium-plasticity ...
An Experimental Investigation of Reactivity Controlled Compression Ignition Combustion in a Single Cylinder Diesel Engine Using Hydrous Ethanol
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dualfuel reactivitycontrolled compression ignition (RCCI) combustion using port injection of a less reactive fuel and earlycycle direct injection (DI) of a more reactive fuel has been shown to yield both high thermal ...
Differential Settlement and Induced Structural Damage in a Cut-and-Cover Subway Tunnel in a Soft Deposit
Publisher: American Society of Civil Engineers
Abstract: This study investigated the differential settlement and induced structural damage in the west extension of Nanjing Metro Line 1. The minimum and maximum cumulative settlements measured over the course of four years of ...
