RISTraffic-Load-Induced Permanent Deformation of Road on Soft Subsoil
Publisher: American Society of Civil Engineers
Abstract: A method for predicting the traffic-load-induced settlement of road on soft subsoil with a low embankment is proposed. The traffic-load-induced dynamic stress in subsoil is calculated by the multilayer elastic theory (not ...
Method for Considering the Effect of Nonuniform Consolidation
Publisher: American Society of Civil Engineers
Abstract: The effect of nonuniform consolidation on the average degree of consolidation (DOC) under the one-dimensional (1D) condition is investigated through a laboratory model test and finite-element analyses (FEAs). Nonuniform ...
Lateral Displacement of Ground Caused by Soil–Cement Column Installation
Publisher: American Society of Civil Engineers
Abstract: Closed form equations for calculating the lateral displacement caused by the installation of soil–cement columns are derived based on cylindrical cavity expansion theory. The radius of the cavity needs to be predetermined ...

Hydraulic Properties of Polymerized Bentonites
Publisher: American Society of Civil Engineers
Abstract: With the goal of increasing the swelling pressure and lowering the permeability of ordinary sodium bentonite with high concentration cation solutions, the optimum conditions for producing polymerized bentonite (PB) were ...
Shimmy Characteristic Analysis for Steering System of Heavy Mining Dump Trucks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Tire wear cost accounts for a large proportion of the total cost of heavy mining dump trucks (HMDTs), and the shimmy of the steering system aggravates the tire wear severely. This study proposes a model-based approach to ...
Simple Method of Modeling PVD-Improved Subsoil
Publisher: American Society of Civil Engineers
Abstract: On a macroscale, the effect of installing prefabricated vertical drains (PVDs) in a subsoil is to increase the mass hydraulic conductivity of the subsoil in the vertical direction. Based on this concept, a simple method ...
Durability against Wetting and Drying Cycles and Installation Damage of Water Hyacinth Geotextiles Coated with Natural Rubber Latex
Publisher: ASCE
Abstract: Water hyacinth (WH) is abundant in tropical regions. As a result of high sources of fiber, the WH is possibly used for producing biodegradable geotextile, but WH-based geotextiles have low tensile strength and durability ...
Pullout Tests Using Steel Grid Reinforcements with Low‐Quality Backfill
Publisher: American Society of Civil Engineers
Abstract: Both laboratory and field pullout tests are conducted using steel grid reinforcements with cohesive‐frictional backfill soils. The laboratory pullout tests are performed using a large‐scale pullout apparatus designed ...
Critical Role of Northern Off-Equatorial Sea Surface Temperature Forcing Associated with Central Pacific El Niño in More Frequent Tropical Cyclone Movements toward East Asia
Publisher: American Meteorological Society
Abstract: bservational records reveal that the number of tropical cyclones (TCs) approaching East Asia in July?October is positively correlated with sea surface temperatures (SSTs) in the equatorial and northern off-equatorial central ...
