Active earth pressure calculation method for gravity retaining wall of railway subgrade based on discretized potential sliding surface inclination angle

Yantu gongcheng xuebao
The cross-section of the backfill behind railway subgrade gravity retaining walls is trapezoidal, and the backfill is subjected to train loads. General formulas of Coulomb earth pressure theory are not applicable for the determination of the location of ...

Prepolymerization Enables On‐Demand Viscosity Tuning for Xolography of Soft Hydrogels

Advanced Science, EarlyView.
A facile in situ prepolymerization strategy enables on‐demand viscosity tuning across three orders of magnitude without external thickeners, transforming low‐viscosity resins into printable formulations for Xolography. The approach suppresses sedimentation, lowers curing dose, enables high‐fidelity support‐free fabrication, and produces advanced ...

Numerical analysis of the backfilling sequence effect on gravity retaining wall behaviour

, 2016
Gravity retaining walls derive their capacity to resist lateral movement through the dead weight of the wall. The design methodologies proposed by standards do not take into account the construction sequences that simulate the process by which the soil ...

Habitat‐Specific Design Strategies for Untethered Soft Robots

Advanced Science, EarlyView.
Habitat shapes the design of untethered soft robots. Across land, water, air, and living tissues, environmental constraints govern viable combinations of compliant structures, actuation mechanisms, and energy delivery. This review connects these constraints with robotic performance and identifies design principles for advancing adaptable, durable, and ...
