Nail Forces and Locus of Maximum Tension of Nailed Cut Subjected to Seismic Excitations: A Calculus Approach with Log-Spiral Failure Surface
(ASCE, 11/1/2021)A vertical cut reinforced with inclined nails subjected to seismic loading was analyzed using the modified pseudodynamic approach, assuming a log-spiral failure surface. A novel calculus-based methodology has been devised ... -
Vertical Vibration of Multiple Flexible Strip Foundations on Multilayered Transversely Isotropic Poroelastic Soils
(ASCE, 11/1/2021)In this paper, vertical vibrations of a group of flexible strip foundations on multilayered transversely isotropic poroelastic soils are presented. The dynamic interaction problem is studied by employing a variational ... -
Earthquake Response of Connected and Unconnected Back-to-Back Geosynthetic-Reinforced Soil Walls
(ASCE, 11/1/2021)A two-dimensional finite-element analysis based on PLAXIS 2D was used to study the behavior of connected and unconnected back-to-back mechanically stabilized earth walls under earthquake loading. The numerical model was ... -
Shaking Table Test on the Seismic Response of a Frame-Type Subway Station in Composite Soil
(ASCE, 11/1/2021)With the development of urbanization, numerous underground structures were constructed in composite soil. It is common that the aseismic capacity of the underground structure is influenced by the soil. Hence, during the ... -
Effect of Total Stress Path and Gas Volume Change on Undrained Shear Strength of Gassy Clay
(ASCE, 11/1/2021)Clay with free gas bubbles can be frequently encountered in the seabed. Gassy clay is an unsaturated soil, but its mechanical behavior cannot be described using conventional unsaturated soil mechanics because it has a ... -
Analysis of Stability of Concealed Cataclinal Slopes with Talus Deposits Accumulated at Their Toes with Respect to Biplanar Failure
(ASCE, 11/1/2021)Talus deposits naturally form to a certain height in the toes of slopes because of the accumulation of collapsed material and small landslides. However, the stability of concealed cataclinal slopes with talus deposits ... -
Experimental and Numerical Investigation on the Dynamic Failure Envelope and Cracking Mechanism of Precompressed Rock under Compression-Shear Loads
(ASCE, 11/1/2021)The complex response of underground geomaterials subjected to dynamic disturbance arises from the microstructure redistribution under high in- situ stress and the resulting fracture behaviors at multiaxial stress states. ... -
Rutting Prediction Model for Semirigid Base Asphalt Pavement Based on Hamburg Wheel Tracking Test
(ASCE, 11/1/2021)Rutting is the main distress of the semirigid base asphalt pavement (SBAP). The rutting prediction model embedded in the Chinese specification was based on the rutting test results of laboratory specimens that show an ... -
A Model of Undrained Stress–Strain Curves Considering Stress Path and Strain Softening
(ASCE, 11/1/2021)The stress path and strain-softening effect have a great influence on the strength and deformation of soils. Former test results show that the strength and deformation behaviors under lateral unloading conditions are quite ... -
