RISIntegral Lifting of a Three-Span Continuous Beam Bridge
Publisher: American Society of Civil Engineers
Abstract: A three-span-continuous girder bridge has to be integrally lifted by 3 m to meet increased navigation capacity. This paper mainly introduces the lifting system mechanism, construction process, and bridge jack-up monitoring. ...
Cost Savings Resulting from Optimum Material Selection
Publisher: American Society of Civil Engineers
Abstract: This paper presents the forensic analysis undertaken on two rehabilitation projects toward highlighting the cost savings achieved by implementing the optimum rehabilitation option and material made from these studies. ...
Aseismic Performance Analysis of Composite Lining Embedded in Saturated Poroelastic Half Space
Publisher: ASCE
Abstract: Earthquakes have been found to seriously threaten the structure of tunnels. To study the seismic performance of a composite lining embedded in a saturated poroelastic half space under an incident P wave, an analytical model ...
Numerical Investigation on Instability of Buildings Caused by Adjacent Deep Excavation
Publisher: ASCE
Abstract: The embedded ratio of retaining structures and improved depth of ground at an excavation base are two key factors for the stability of deep excavation. For a collapsed excavation in soft clay in Hangzhou, China, a numerical ...
New Technique for Ground Vibration Mitigation by Horizontally Buried Hollow Pipes
Publisher: ASCE
Abstract: Mitigating the ground vibration initiated by the passage of trains to safeguard the surrounding structures is a challenge for geotechnical engineers. Among various existing methods, open trenches are one of the most common ...
Simplified Theoretical Prediction for Lateral Deformation of a Diaphragm Wall Using the General Third-Order Plate Theory
Publisher: ASCE
Abstract: The diaphragm wall is widely used in deep excavation engineering to guarantee the safety of the foundation pit and surrounding environment during excavation. An accurate prediction of the lateral deformation of the diaphragm ...
Semianalytical Method for Controlling the Deformation of Retaining Structures Subjected to Asymmetrical Loads
Publisher: ASCE
Abstract: In excavation engineering, most of the retaining structures are subjected to asymmetrical loads, including in asymmetrical excavation and asymmetrical overloading. However, a theoretical solution to, and deformation-controlling ...
Performance Evaluation of Long Pipe Roof for Tunneling below Existing Highway Based on Field Tests and Numerical Analysis: Case Study
Publisher: American Society of Civil Engineers
Dynamic Deformation Control of Retaining Structures of a Deep Excavation
Publisher: American Society of Civil Engineers
Abstract: Many uncertain factors in the excavation process may lead to excessive deformations and internal forces of retaining structures; therefore, the design of deep excavations should be adjusted according to real-time monitoring ...
