RISEvolution of Soil Arching Subjected to Dynamic Loads
Publisher: ASCE
Abstract: The Loess Plateau in Northwest China is located in a seismic area. Therefore, the high-filled cut-and-cover tunnels (HFCCTs) in this area are subjected to high earthquake risk. The load reduction measure of laying an ...
Evolution of Load Reduction for High-Filled Cut-and-Cover Tunnels Subjected to Soil Creep
Publisher: ASCE
Abstract: The excessive load from the high embankments of high-filled cut-and-cover tunnels (HFCCTs) threatens the safety and stability of HFCCTs. Relatively low-compacted (RLC) soil can reduce such loads in the short term, but the ...
Semianalytical Model of Unloading-Induced Pore-Water Pressure and Consequent Consolidation Settlement of Surcharge Preloading Railway Subgrade
Publisher: ASCE
Abstract: Surcharge preloading is a suitable foundation treatment for high-speed railways in soft soil regions. As a temporary preload on the foundation, the surcharge load must be removed before track construction. In this process, ...
Coupled Effect of Expanded Polystyrene and Geogrid on Load Reduction for High-Filled Cut-and-Cover Tunnels Using the Discrete-Element Method
Publisher: ASCE
Abstract: High-filled cut-and-cover tunnels (HFCCTs) can be used to reclaim usable land due to the unique landforms in western China. The load reduction methods used to reduce the earth pressure on such cut-and-cover tunnels (CCTs) ...
