RISAccuracy of Pull Force Estimation for Steel Pipe Installations Using Horizontal Directional Drilling: Review of 200 Case Studies
Publisher: ASCE
Abstract: Pull force estimation in horizontal directional drilling (HDD) is an essential step during the planning phases. Pull force calculation can be relatively complicated when considering variations during the HDD construction ...
Review of Machine Learning Algorithms for Automatic Detection of Underground Objects in GPR Images
Publisher: ASCE
Abstract: Ground-penetrating radar (GPR) is a nondestructive tool that has gained popularity after giving promising results in different areas—such as utility engineering, transportation engineering, civil engineering, and geology—with ...
Estimation of Maximum Annular Pressure during HDD in Noncohesive Soils
Publisher: American Society of Civil Engineers
Abstract: This study investigated the effectiveness of estimating the maximum allowable annular pressure during horizontal directional drilling (HDD) in noncohesive soils by using two theoretical cavity-expansion solutions (small ...
Compression Behavior of Large-Sized Tire-Derived Aggregate for Embankment Application
Publisher: American Society of Civil Engineers
Abstract: Tire-derived aggregate (TDA) has been successfully used for highway embankment applications in the past. Previous applications mainly used small and medium tire sizes as TDA sources. There are no published test results in ...
Survey of Practice and Literature Review on Municipal Road Winter Maintenance in Canada
Publisher: American Society of Civil Engineers
Abstract: Efficiency of winter operations is essential for cities in cold regions because fiscal budgets are limited and excessive amounts of street sand and salt can negatively impact the environment. A review of winter maintenance ...
Modeling Microtunnel Boring Machine Penetration Rate Using a Mechanistic Approach
Publisher: ASCE
Abstract: Predicting the productivity of microtunneling construction projects is challenging, due to the complexities of this trenchless excavation method. One of these complexities is estimating the microtunnel boring machine (MTBM) ...
Mechanistic Modeling of Cutterhead-Ground Engagement Influence on Microtunnel Boring Machine Penetration Rate
Publisher: American Society of Civil Engineers
Abstract: Planning of a microtunneling project requires prediction of microtunnel boring machine (MTBM) performance. One of the main performance indicators of MTBMs is the penetration rate. The prediction of MTBM penetration rate ...
Automatic Detection and Classification of Underground Objects in Ground Penetrating Radar Images Using Machine Learning
Publisher: ASCE
Abstract: Ground penetrating radar (GPR) is widely used in subsurface utility mapping. It is a nondestructive tool that has gained popularity in supporting underground drilling projects such as horizontal directional drilling (HDD). ...
