Changes in the Stability of a Superhigh-Deposit Slope Considering the Influence of Seepage Erosion
(American Society of Civil Engineers, 2024)Rainfall can cause seepage erosion of the fine particles in soil (FPS) within the wide grading of particles present in a deposit slope, reducing its strength and eventually leading to a landslide. Unfortunately, there is ... -
Deformation Characteristics and Noncoaxial Behavior of Fiber-Reinforced Soil under Pure Principal Stress Axis Rotation
(American Society of Civil Engineers, 2024)Geomechanics tests and theories have confirmed that soil exhibits noncoaxial behavior under the rotation of principal stress. A series of hollow torsional shear tests were conducted in this study on fiber-reinforced soil ... -
Experimental Study on Load-Transfer Mechanism of Rockbolts Using Fiber Optic and Strain Gauge Monitoring
(American Society of Civil Engineers, 2024)As a cost-effective rock-supporting method, rockbolts have been widely used in geotechnical and mining engineering. Better understanding the load-transfer mechanism of rockbolts is of great importance for improving the ... -
Bearing Capacity of Foundations over Rock Slopes–Slip Lines and FELA Solutions
(American Society of Civil Engineers, 2024)The ultimate bearing capacity of a strip footing placed horizontally over the edge of a sloping rock mass has been determined on the basis of the stress characteristics method (SCM) using the generalized Hoek–Brown yield ... -
Calibration of the Resistance Factors for the LRFD of Shallow Foundations of Transmission Towers under Uplift Loading
(American Society of Civil Engineers, 2024)Over the last few decades, reliability-based design methods have been widely implemented into the foundation design practice. However, several design codes for transmission tower foundations are still based on the allowable ... -
Performance and Mechanism of Double-Row Capsule Grouting to Protect Tunnels Adjacent to Excavation
(American Society of Civil Engineers, 2024)A new grouting technique, double-row capsule grouting (DRCG), has been developed and implemented in practice. This grouting technique could effectively mitigate excavation-induced tunnel movement and ensure the serviceability ... -
Active Earth Pressure Calculation of Equilateral Convex Corners in Excavation Engineering
(American Society of Civil Engineers, 2024)The presence of convex corners will affect the earth pressure calculation, but there is a paucity of studies on calculating the ground pressure of convex corners in excavation engineering. To address this issue, equilateral ... -
Probabilistic Seismic Stability Analysis of Reinforced Soil Retaining Structures in Partially Saturated Conditions
(American Society of Civil Engineers, 2024)The conventional design of reinforced soil retaining structures (RSRS) assumes a dry or fully saturated backfill in a deterministic approach, which may not reflect real-field conditions accurately. While there are ongoing ... -
Axial Force Coherence Study of Servo Steel Strut Loading in Soft-Soil Deep Excavation
(American Society of Civil Engineers, 2024)The coherence of axial force between steel struts in excavation (axial force coherence) is an important factor affecting the axial force control of servo struts. To understand the law of axial force loss of adjacent struts ... -
A Simplified Calculation Method for the Shear Strength of Unsaturated Silt
(American Society of Civil Engineers, 2024)The matric suction must be measured when calculating the shear strength of unsaturated silt, but the measurement method is cumbersome and time-consuming. The saturation degree of silt is easily measured; therefore, a ... -
Physical and Chemical Properties of Bentonite Modified by Electrochemical Treatment
