RISHigh-Precision Trigonometric Leveling Based on Correction with Atmospheric Refraction Coefficient Model
Publisher: ASCE
Abstract: When an electromagnetic wave passes through the atmosphere, due to variation of atmospheric parameters, its propagation path is usually altered and the propagation speed also changes. Therefore, errors will be induced in ...
Investigation of Infiltration Loss in North Central Texas by Retrieving Initial Abstraction and Constant Loss from Observed Rainfall and Runoff Events
Publisher: American Society of Civil Engineers
Abstract: Accurate modeling of infiltration losses is vital for runoff estimation and thus the development of flood design/protection criteria and water management schemes, etc. In design flood practices, the initial abstraction and ...
Theoretical and Experimental Study on Elastic–Plastic–Sliding Load Transfer Model for Pile Tip and Pile Side Postgrouting Piles
Publisher: American Society of Civil Engineers
Abstract: An elastic–plastic–sliding trilinear load transfer model is established for grouted piles. This model summarizes the resistance–displacement relationships at both the side and tip of the pile, describing the transition ...
Theoretical Analysis of Pile Tip and Pile Side Compaction Grouting and Grout Diffusion Height Considering Unloading Effect
Publisher: American Society of Civil Engineers
Abstract: This study introduces a unified cylindrical and spherical cavity reverse expansion model to simulate the formation of compaction grouting bodies and grout diffusion along pile shafts. Stress field expression employs the ...

Evaluation of Multiradar Multisensor and Stage IV Quantitative Precipitation Estimates during Hurricane Harvey
Publisher: ASCE
Abstract: Radar-based quantitative precipitation estimate (QPE) serves as input for flood forecasting, and its importance gets magnified during catastrophic storms, e.g., Hurricane Harvey in 2017. The record-breaking rainfall ...
Modeling of Compaction Grouting Considering the Soil Unloading Effect
Publisher: ASCE
Abstract: Previous studies have given little consideration to the influence of the soil unloading effect on compaction grouting. The theoretical relationship model between the soil unloading degree and the soil deformation modulus ...
Guided Wave Excitation and Sensing in Constant Irregular Cross Section Structures with the Semianalytical Finite-Element Method
Publisher: ASCE
Abstract: Guided waves play an important role in practical structural health monitoring (SHM) systems. Due to the complexity of irregular cross sections, there has been little research on guided wave modal control done using excitation ...
A Modified <i>p</i>-<i>y</i> Hyperbolic Model Considering the Soil Unloading Effect for the Bored Pile
Publisher: American Society of Civil Engineers
Abstract: The effect of soil radial unloading existing in the bored pile hole excavation process can weaken the bearing capacity of pile foundations, and the relevant theoretical method of calculating the pile horizontal bearing ...
